Zhang Lei is 49 years old this year，Tall and thin、Stand upright，Under black half-rimmed glasses，A pair of eyes showing kindness and humility。Elegance，This is the first impression he leaves on people。This temperament also extends to his 188bet mobile login works。
As the deputy chief engineer of the Civil Engineering Institute of 188bet Design Group Co., Ltd.，Zhang Lei tirelessly pursues the perfect integration of technology and art in the design of railway bridges。27 years in business，He participated in the design of more than 100 railway bridges, large and small，Connecting the developed road network，Dotted among the magnificent mountains and rivers of the motherland。
Bravely reaching the peak of 188bet mobile login technology
Coast of the East China Sea，On the vast waters of Hangzhou Bay，The world’s first strong tidal bay cross-sea bridge - Nantong to Ningbo high-speed rail Hangzhou Bay cross-sea 188bet mobile login initially appears impressive。As the bridge professional chief engineer of the bridge，Every once in a while，Zhang Lei will bring his camera to the construction site，While inspecting, the process of the bridge from blueprint to reality was recorded。
Hangzhou Bay，Qiantang River Estuary，One of the three largest strong tide bays in the world，The sea is wide、The wind is strong and the tide is strong。In such a complex and harsh marine environment，To design and build a collection of long-span, long-jointed high piers、Ultra-low water resistance、Ultra-long cross-sea high-speed 188bet mobile login with driven-in ultra-long steel pipe pile foundation equal to one body，It’s not easy。
Infinite scenery on the dangerous peak。"As a 188bet mobile login designer，Can you encounter such a project，is very lucky and glorious。"Zhang Lei said。
Since joining the work，Zhang Lei has personally experienced and witnessed the rapid development of China’s railways。In this magnificent journey，China has successfully mastered world-class long-span 188bet mobile login construction technology。The vast waters，The world’s first kilometer-level cable-stayed bridge for both road and rail, the Shanghai-Suzhou-Tongji Railway and the Shanghai-Suzhou-Tongyang Yangtze River Road-rail Bridge look like a flying rainbow；Difficult and dangerous mountainous areas，Shanghai-Kunming High-Speed Railway Beipanjiang Bridge、A number of world-class long-span arch bridges such as the Dali-Ruili Railway Nujiang Bridge stand majestically... one 188bet mobile login after another crosses mountains and valleys、Unimpeded rivers and seas，Connecting the world's largest high-speed rail network and advanced rail network，Write a magnificent chapter in the high-quality development of China’s railways。
"As an important part of the transportation system，Railway bridges are a reflection of a country’s comprehensive national strength。"Zhang Lei said。The Hangzhou Bay Cross-sea 188bet mobile login is currently under construction，It is currently the longest under construction in the world、Highest construction standards、The fastest high-speed railway cross-sea bridge，A milestone in the field of world 188bet mobile login construction。
In this super project，The main span of the north channel bridge of the Hangzhou Bay Cross-sea 188bet mobile login designed by Zhang Lei and his team is 450 meters，It is the world's largest span ballastless track twin towers double cable plane steel box - steel truss composite girder cable-stayed bridge，The longest joint length of its approach bridge at sea reaches 3.08 kilometers。
In order to successfully build an ultra-long cross-sea 188bet mobile login，Zhang Lei led his team to review more than a dozen cross-ocean engineering technical materials at home and abroad，Repeatedly demonstrate and revise multiple design research plans，Insisting on in-depth investigation of the 188bet mobile login site with strong winds, waves and tides...for nearly 3 months，He has seen almost every sunrise on Hangzhou Bay。
"People at that time used the rising and falling tide to install bridges，Why can’t we？”At a seminar，Zhang Lei suddenly thought of Quanzhou Luoyang 188bet mobile login—the earliest existing cross-sea beam-type stone 188bet mobile login in my country，The 188bet mobile login construction technology of "floating girder" is an important invention in Chinese history。Follow this idea，Zhang Lei proposed "prefabrication of whole hole beams，Using ship floating crane installation，Construction plan that then connects them into continuous beams，Finally successfully solved the construction problem of ultra-long cross-sea bridges at sea。
December 2022，Zhang Lei and his team completed the bridge engineering design work for the north channel bridge and the sea approach bridge of the Hangzhou Bay Cross-sea 188bet mobile login。The moment the design drawings are delivered，He was filled with emotions。over the years，He and his team have achieved many “firsts”，Measuring the progress of China’s railway——
Beijing-Shanghai High-speed Railway Tianjin Hub Tianjin-Shanghai Connection Line Extra Large Bridge，Innovative application of concrete three-tower low-tower cable-stayed bridge、New technologies such as split wire tube cable saddle and so on，Becomes my country’s first railway prestressed concrete low tower cable-stayed bridge；Beijing-Guangzhou High-speed Railway Zhengzhou Yellow River Road-rail Dual-purpose Bridge，Innovative use of multi-tower long-jointed steel truss cable-stayed bridge style、New structures such as spatial three-main truss structure with inclined side girders，Becomes my country’s first diagonal main truss multi-tower road-rail cable-stayed bridge；Tongjiang China-Russia Heilongjiang 188bet mobile login，Successfully applied the new steel truss form、New technologies such as new bridge deck system and new ballastless track structure，Becoming the first cross-river 188bet mobile login between China and Russia...one after another，Write a vivid footnote for accelerating the construction of my country's modern railway infrastructure system。
Injecting artistic value into the steel frame
What is the design life of a 188bet mobile login?
One hundred years.
"Every 188bet mobile login is a huge project，It will stand there for a hundred years after it is completed，So bridges are not just structures that lead to the other side，It is a kind of humanistic landscape that will last forever。”Zhang Lei doesn’t talk much，Talk about the art of design，But he is in high spirits。
After graduating from university，Zhang Lei entered the then Third Survey and Design Institute of the Ministry of Railways and became a 188bet mobile login design engineer。The bridge design plan he submitted，While meeting basic functions，It also gives the bridge unique artistic value，Refreshing。
The first major 188bet mobile login engineering project that Zhang Lei participated in the design，It is the Qinghai-Tibet 188bet mobile login Lhasa River Extra Large Bridge。The beginning of design，In order for the bridge to be perfectly integrated into this magnificent and vast picture，Zhang Lei took to the streets of Lhasa to collect stories，The Hada that will be seen、prayer flags、Snow Mountain、Snow lotus and other elements are turned into design inspiration。
Finally，In their design plan for the Lhasa River 188bet mobile login，The 188bet mobile login is designed in white with three continuous spans of arches，Like a long white hada flying in the Lhasa Valley。
This plan won the bid in first place，After completion, the Lhasa River Bridge has been widely praised by all walks of life，Becoming a landmark project of the Qinghai-Tibet 188bet mobile login。
From now on，The concept of integrating cultural elements and aesthetic taste into 188bet mobile login structure and shape design，deeply rooted in Zhang Lei’s heart。His home，Collect a large number of classics about ancient bridges，Whenever I have time，He will study it。After work，He likes to visit ancient bridges all over the country，Decades，He has visited nearly a hundred bridges across the country。
2020，Zhang Lei and his team received the design task of the Dongying Yellow River Highway-188bet mobile login for the Tianjin-Weihai High-Speed Railway。This is a road-rail cable-stayed bridge with a main span of 600 meters，It is also the bridge with the longest span in the Yellow River Basin。
Considering that the 188bet mobile login site is located in Qilu，The region has a long history，Profound cultural heritage，Zhang Lei visited Qufu Confucius Temple several times in succession，Studyed the Lingxing Gate、Side kick、Arise、Sparrow and other traditional Chinese architectural elements，Finally apply these elements in the design。
"When we were designing，Strive to perfectly integrate the 188bet mobile login with the surrounding natural and cultural environment，Not only in terms of aesthetics, we must inherit traditional Chinese architectural aesthetics，It must also reflect the continuity of Chinese traditional culture。" Zhang Lei said，The 188bet mobile login is currently under construction，Will cross the Yellow River in the near future，Become one of the local iconic landscapes。
Over the years，Zhang Lei condenses his aesthetic pursuit on each bridge。He is responsible for the landscape design of the Haqi Passenger 188bet mobile login Songhua River Bridge，Use the unique bridge style like undulating mountains to set off the roaring river；He presided over the design of the Hangzhou-Taiwan High-speed 188bet mobile login Jiaojiang Bridge，Slimness and harmony，Elegant style，The supple white cable stays contrast with the blue sea and sky...
Connecting mountains and rivers，Feihong picturesque。With excellent skills，Zhang Lei carves every 188bet mobile login into a beautiful blend of technology and art，Added countless beautiful scenery to the motherland。
Draw wisdom from traditional culture
Zhang Lei grew up in Datong, Shanxi, a famous historical and cultural city，Both parents are 188bet mobile login employees，My childhood home is near the 188bet mobile login line。The white mist emitted by the steam engine，The long whistle of the train as it goes away，Coupled with the strong cultural atmosphere of the ancient capital，Together constitute Zhang Lei’s childhood life picture。
A person’s life is a process of constantly looking back at his hometown。As we grow older，How to combine your 188bet mobile login work with traditional culture，Becomes a new proposition for Zhang Lei’s thinking。
"Traditional culture embodies the deepest spiritual pursuit of the Chinese nation，We should draw strength from China’s excellent traditional culture。" Zhang Lei said。
In the design of long-span steel truss-stiffened continuous beams for Zhengfu High-speed 188bet mobile login，Because the main span of the continuous beam is 172 meters long，The expansion and contraction displacement generated at the beam end will be relatively large，Need to set rail telescopic adjuster，But this section of the line is a curve，It is not suitable to set the regulator。
"To set or not to set？”Can’t find a suitable solution at the moment。A night of hard thinking，Zhang Lei, who is familiar with ancient books, suddenly thought of a sentence in "The Analects of Confucius: Politics", "Do what you want without going beyond the rules."，He picked up the pen excitedly，Hurry to write down this moment of inspiration。
Early the next morning，Zhang Lei convened the team: "'Following one's own desires' and 'not exceeding the rules' are both contradictory and unified.，Applies to bridges，We can give bridges limited freedom，Let the two ends of the beam bisect the total expansion，This can reduce the amount of telescopicity at the remote end，There is no need to set the regulator。”
The collision of traditional culture and modern industry，Break the mindset and path dependence of past bridge design。Zhang Lei led the team to develop a "limited freedom constraint system" and a limiting device with adjustable functions，Successfully realized the long-span continuous beam of 188bet mobile login without the need for rail telescopic adjuster。This is an important innovation proposed by our country in the field of 188bet mobile login bridges in the world。
2021，Zhang Lei combines many years of 188bet mobile login design experience and in-depth thinking on 188bet mobile login engineering，Published the monograph "The Way of Bridges--The Enlightenment of Chinese Philosophical Thoughts on 188bet mobile login Engineering"，Causing great repercussions in the industry。He will philosophy、Integration of architectural aesthetics and engineering，Breaking the barriers and boundaries of traditional disciplines，In the traditional culture of the Chinese nation, “all things grow together without harming each other，The philosophy of "Tao runs parallel without conflicting"，Expressed his persistence in craftsmanship and cultural consciousness。
In the design of the towers of the Dongying Yellow River Highway and 188bet mobile login on the Tianjin-Weihai High-speed Railway，Zhang Lei pioneered the use of a new cable-beam anchoring structure cross-anchored in core concrete，Convenient for construction，Significantly reduced the project cost，This is the inspiration he got from Mozi’s thoughts and ideas of making use of things to benefit the people。
In the design of large cable-stayed bridges such as the North Channel 188bet mobile login of the Hangzhou Bay Cross-Sea 188bet mobile login，Zhang Lei designed a structure that combines strength and softness，Utilizing the flexibility of the cable-stayed system and the setting of dampers，Let bridges overcome rigidity with softness during earthquakes，To better achieve the effect of shock absorption，This is the inspiration he got from Laozi’s dialectical thought。
"Chinese excellent traditional culture is the crystallization of the wisdom of Chinese civilization，It is the root and soul of the Chinese nation，It is the foundation for us to stand firm in the turmoil of world culture。”The call of the times，Let Zhang Lei be more determined to use 188bet mobile login bridges as a carrier，Inheriting the unique wisdom of the Chinese nation。
Changhong Flying Frame，Embodying the skills and ingenuity of Zhang Lei and his team，The wheels and rails that hold up China’s high-speed rail，The road to the future of independent innovation，The road leading to the practice of Chinese-style modernization。
