混凝土箱梁斜拉桥极限状态研究

On ultimate status of concrete box girder cable-stayed bridge

根据济南黄河大桥的实际参数,建立了该斜拉桥有限元模型,分析了桥梁的极限状态,提出了以极限状态为基础的预警指标体系,解决了该桥预警体系缺失的问题。

According to the factual parameter of Huanghe Bridge in Jinan,the paper establishes the finite element model for the cable-stayed bridge,analyzes its ultimate status,and points out the warning index system based on the ultimate status,so as to solve the defects of the warning system of the bridge.
