斜拉桥牵索挂篮优化设计分析

Optimization design analysis of the cable basket of stay-cable bridge

对牵索挂篮进行了优化设计,并对结果进行了比较,表明采用的优化方法是有效和可行的,分析了挂篮各种工况的应力,对牵索挂篮进行了板壳元模拟分析,以更加真实地模拟挂篮各种工况下的内力和变形,确保桥梁悬臂浇筑施工中的安全。

It makes an optimization design of cable basket, and makes a comparison of the result. The result shows the optimization method in this article is effective and feasible. It makes an analysis of the stress of basket under every conditions and makes a shell element simulated analysis of cable basket, which better simulates the interior force and deformation of basket under different conditions, to assure the safety of bridge cantilever construction.
