市政道路施工对既有地下国铁站房的安全影响分析

Analysis on the Safety Infl uence of Municipal Road Construction on Existing Underground National Railway Station Building

随着高铁的迅猛发展,铁路运营速度越来越快,铁路车辆对变形越来越敏感。地下国铁站房上方进行卸载和堆载作业,均会引起站房内力变化和轨道变形。文章采用Midas Gen软件建立三维模型,分析了市政道路施工对既有地下国铁站房的安全影响,旨在为铁路站房上方作业提供理论支撑,并对上方作业提出优化建议。

With the rapid development of high-speed railway,the operating speed of railway is getting faster and faster,and railway vehicles are becoming more and more sensitive to deformation.The unloading and stacking operations above the underground national railway station building will cause the internal force change and track deformation of the station building.Midas Gen software is used to establish a three-dimensional model,and the safety influence of municipal road construction on the existing underground national railway station building is analyzed.The purpose is to provide theoretical support for the operation above the railway station building,and put forward optimization suggestions for the above operation.
