公路下穿某铁路桥梁的基础位移问题探究

Study on foundation displacement problems of highway under-passing the railway bridge beam

结合东北某新建公路下穿某铁路桥梁的基本情况,建立了公路结构计算模型,对公路建设的三种工况进行了数值模拟,分析了桥墩承台的位移特征,有利于提升公路建设的安全性,降低公路建设对铁路桥梁的影响。

Combining with basic conditions of the new northeast highway under-passing the railway bridge,the paper establishes the highway structure calculation model,carries out numerical simulation of three kinds of highway construction conditions,and analyzes the displacement features of the bridge pier cushion cap,which will be good for improving highway construction safety and reducing the impact of highway construction upon the railway bridge.
