The Construction Control Simulation Analysis Of Cable-stayed Bridge

The construction control simulation analysis of cable-stayed bridge is the foundation of the construction control, and it includes two parts: the determination of the finished bridge state and the determination of the construction state. The finished bridge state is one of the cable-stayed bridge research focuses. And in the course of constructing bridge, because the construction state directly concerns the construction techniques and the construction control, it shows out its much important practicality values. And because the finished bridge state associates directly with its construction state, so, it is very important to study how to obtain the proper bridge construction state.Making reference to the AnQing ChangJiang River Highway Bridge construction and the construction control, firstly, this paper studies the philosophy of the cable-stayed bridge construction control simulation analysis systematically, and pays much attention to the theory of simulating the construction process: backward analysis and forward analysis. Then on the basis of introducing the construction process of the AnQing ChangJiang River Highway Bridge, analysis the construction course fully, and analysis comparatively the result of each girder segment construction simulation, and study the variation philosophy of the line style of large cable-stayed bridge during construction.
