The best bridge building employment specialization

Construction bridge employment best professional:

Bridge engineering professional employment direction and employment prospects: to the Highway Administration, the Transportation Bureau and other transportation civil engineering management department as infrastructure section, researcher, etc.; to the provincial highway bureaus, road and bridge companies, municipal corporations and other front-line construction units as constructors, technicians, surveyors, quality inspectors, materials, experimenters, etc.; to the supervision company as a general supervisor. The company has also been working as a general supervisor in the supervisory company.

Bridge engineering refers to the work process of bridge survey, design, construction, maintenance and verification, as well as the study of this process of science and engineering technology, it is a branch of civil engineering. The development of bridge engineering depends mainly on the need of transportation for it.

Bridge engineering mainly studies the design of bridge crossing, decide the bridge aperture, consider the navigation and line requirements to determine the height of the bridge deck, consider the substrate is not subject to scouring or freezing to determine the depth of the foundation, the design of diversionary buildings, etc.; bridge design; bridge structural design; bridge construction; bridge verification; bridge testing; bridge maintenance and other aspects.

Ancient bridges to pass people and animals, the main load is not large, the bridge deck slope can be steeper, and even paved steps. Since the railroad, the bridge to bear the load doubled, the line of the slope and curve standard requirements and high, and the need to build a railroad network to increase economic benefits, therefore, to cross the larger and deeper rivers and canyons, forcing the bridge to the development of large span.

In terms of materials for building bridges, high strength, light weight, low cost as the main basis for the choice, still to develop the traditional steel and concrete-based, improve its strength and durability. Stone, wood, cast iron, wrought iron and other bridge materials, obviously not required, and the mass production of steel just to meet this requirement.

Bridge engineering construction:

In bridge construction, the construction organization will make full use of electronic computers for cost-effective management. In the construction technology, will continue to quote the new technology and high efficiency, high function of the machinery and equipment, in order to improve the quality, shorten the construction period, reduce the cost.
