摘　　要：为了尽量降低地铁车站施工对地面交通的影响,盖挖法是经常采用的一种施工方法。其中构建一个稳定、可靠的临时路面系统是盖挖法施工中的一个关健环节。结合城市轨道交通某地下车站实际工程,运用空间有限元分析软件MIDAS/Civil进行整体分析,验算军用梁各部位内力及变形,获得了可靠的结论,得出证明该方案的合理性和可行性,给出了盖挖临时路面结构方案的设计建议,同时为盖挖法临时路面体系设计计算提供了一般原则。In order to minimize the impact of metro station construction on ground traffic,covered excavation is a common construction method.Constructing a stable and reliable temporary pavement system is a key link in the construction of covered excavation.Combining with the actual project of a underground station,this paper makes an overall analysis using the spatial finite element analysis software MIDAS/Civil,checks the internal forces and deformation of each part of the military beam,and obtains reliable conclusions to prove that the scheme is reasonable and feasible.This paper also gives the design suggestions for the structure scheme of the temporary pavement covered excavation,and provides general principles for the design and calculation of the temporary pavement system in covered excavation.
