摘要
随着我国城镇化发展进程的加快,城市道路和市域铁路工程建设规模也日趋庞大,道路工程与市域铁路出现交叉的情况越来越多。以某新建城市道路工程并行既有市域铁路桥梁为例,总结市域铁路桥梁变形控制标准,并分析新建道路工程中偏压荷载、填方堆载等工况对既有市域铁路桥梁结构的影响,以制订合理的设计施工方案,确保市域铁路运营安全,为类似工程提供参考。
With the acceleration of urbanization development in China,the construction scale of urban roads and urban railways is becoming increasingly large,and there are more and more intersections between road engineering and urban railways.This article takes a newly-built urban road project and an existing urban railway bridge as an example to summarize the deformation control standards of urban railway bridges,and analyze the impact of conditions such as eccentric load and fill stacking load on the structure of existing urban railway bridges in the newly-built road project,in order to develop a reasonable design and construction plan,ensure the safety of urban railway operation,and provide reference for similar projects.
