What is the development direction of all aspects of bridge engineering?

Bridge engineering refers to the working process of bridge survey, design, construction, maintenance and verification, as well as the science and engineering technology to study this process. It is a branch of civil engineering. The development of bridge engineering mainly depends on the needs of transportation. What is the development direction of all aspects of bridge engineering?

I. Technical aspects

Bridge engineering mainly studies the bridge span design, determines the bridge diameter, determines the height of the bridge deck considering the navigation and line requirements, determines the buried depth of the foundation considering the non-scouring or frost heaving of the basement, and designs diversion structures. Bridge scheme design; Bridge structural design; Bridge construction; Bridge grade; Bridge testing; Bridge maintenance and so on.

Second, the material aspect.

In terms of bridge building materials, high strength, light weight and low cost are the main selection basis, and traditional steel and concrete are still the main ways to improve strength and durability.

Third, the construction.

In bridge construction, the construction organization will make full use of computers for economic and effective management. In terms of construction technology, new technologies and high-efficiency and high-performance mechanical equipment are constantly introduced to improve quality, shorten construction period and reduce costs.

1, bridge substructure construction

Pier construction: integral pier construction, including stone pier and concrete pier; Construction of assembled pier; Block pier construction; Column pier construction

Pier foundation construction: open excavation to expand foundation construction; Pile foundation and pipeline foundation construction; Open caisson foundation construction;

2, the bridge superstructure construction

Bridge load-bearing structure construction: cast-in-place support method; Precast installation method; Cantilever construction method; Rotating construction method; Pushing construction method; Construction method of main hole of movable formwork; Lateral movement method; Lifting flotation method

3, beam bridge construction

Simply supported beam bridge, continuous beam bridge with equal section, prestressed concrete continuous beam bridge with variable section, prestressed concrete continuous steel structure bridge, steel beam bridge.

Fourth, maintenance

In bridge maintenance inspection, new precision measuring instruments, such as acoustic measurement, are introduced to measure the defects and elastic modulus of structural materials; Check the crystal structure of steel with hand-held metallographic camera, so as to reinforce it as early as possible, prevent problems before they happen, and thus prolong the service life of the bridge.

Under the comprehensive influence of production development and all kinds of scientific and technological progress, bridge engineering has always been developing continuously, following the principles of applicability, safety, economy and beauty.
