整体式桥梁路桥结合部位受力分析

Analysis of Stress at Connection Position between Road and Integral Bridge

"桥头跳车"是公路建设中常见的通病之一,是道路交通安全的重要隐患。分析了整体式桥梁路桥结合部位复合地基受力特点,找出影响搭板沉降的原因;计算建立了整体式桥梁桥头复合地基处理的三维有限元分析模型,为针对性地改善措施提供了理论基础。

'Vehicle bumping at the connection position between road and bridge' is one of common faults in highway construction and is also a potential risk for road traffic. The stress characteristics of composite foundation at the connection position between road and integral bridge are analyzed, and the reasons for the settlement of the connection slab are found out. The three-dimensional finite element analysis model of the composite foundation at the connection position between road and integral bridge is established, which provides the theoretical basis for the improvement measures.
