菖蒲港大桥桥梁荷载试验仿真分析

Simulation Analysis on Load Test of Bridge over Changpu Port

依据《通城县菖蒲港桥扩建工程施工图设计》及相关文件建立模型,为加载计算提供基本计算模型,按照现行规范验算了控制截面在设计荷载作用下的内力、应力、变形等效应,确定了加载车辆数、加载位置、加载效率,经过将荷载作用下的效应值和模型计算的计算值对比,得出菖蒲港大桥承载力、刚度、裂缝均满足要求。

Basing on Construction Drawing Design of Extension Project for Bridge over Changpu Port in Tongcheng County and relevant documents,the model is built. In order to provide basic calculation model for loading calculation,the checking calculation on effects like internal force,stress,deformation and so on of control section under the influence of design load is made according to current code,so as to determine the number of loading vehicle,loading position,and loading efficiency. We can conclude that the bearing capacity,rigidity and crack of the bridge over Changpu port meet the requirements by comparing the effect size under the influence of load and calculated value of model calculation.
