摘　　要：随着城市化进程的加速,地铁建设已成为解决城市交通问题的重要手段。然而地铁隧道的施工和运行对周边环境,特别是对地下管线系统的影响不容忽视。原水管道作为城市基础设施的重要组成部分,其结构安全直接关系到城市的供水安全和稳定。因此,通过数值模拟方法,探究地铁隧道施工及运行期对原水管道结构安全的影响。以深圳市三号线地铁下穿东清输水管线工程为例,采用MIDAS-GTS软件建立三维数值模型,分析原水管道在地铁隧道施工及运行期的应力、应变、位移等变化情况。同时,结合工程实际情况,评估原水管道的结构安全状况。With the acceleration of urbanization process,subway construction has become an important means to solve urban transportation problems.However,the construction and operation of subway tunnels cannot be ignored for their impact on the surrounding environment,especially the underground pipeline system.As an important component of urban infrastructure,the structural safety of raw water pipelines is directly related to the safety and stability of urban water supply.Therefore,the impact of subway tunnel construction and operation period on the structural safety of raw water pipelines through numerical simulation methods are explored in depth.This article takes the Dongqing water transmission pipeline project under a subway line in Shenzhen as an example,and uses MIDAS-GTS software to conduct a three-dimensional numerical model to analyze the stress,strain,displacement and other changes of the raw water pipeline during subway tunnel construction and operation.Meanwhile,based on the actual situation of the project,evaluate the structural safety status of the raw water pipeline.
