曲率半径变化对曲线梁桥墩顶荷载特性影响分析

Analysis of the Influence of Curvature Radius Change on Load Characteristics of Pier Top of Curved Beam

在现代化桥梁建设中,曲线梁桥应用越来越多,曲线梁桥由于“弯扭耦合”效应的存在使其墩顶的荷载特性受力比较复杂。以某曲线梁桥为例,运用Midas civil针对曲线梁桥分别从恒荷载、温度力、制动力、预应力、移动荷载等方面进行分析,得到各种荷载作用下曲线梁桥墩顶荷载分布情况,为后续曲线梁桥下部结构设计提供工程参考。

In the construction of modern bridges,curved beam bridges are used more and more.Due to the"bending-torsion coupling"effect,the load characteristics of the curved beam bridge are more complicated.Taking a curved beam bridge as an example,Midas civil is used to analyze the dead load,temperature force,braking force,prestress,moving load and other aspects of the curved beam bridge.The distribution of the top load of the curved beam bridge pier under various loads is obtained,which provides engineering reference for the subsequent design of the substructure of the curved beam bridge.
