摘　　要：为了更好地分析邻近地铁车站的深基坑施工对邻近车站和隧道的影响机理,对福州某深基坑项目进行研究和分析。首先对项目基本情况、既有车站现状和深基坑支撑方案进行梳理,在此基础上,研究分析影响周边车站正常运营的影响因素。借助有限元分析软件Midas,对总体施工过程进行分工况地受力模拟分析,对车站的结构位移、结构内力和净空收敛等情况进行数值分析。通过研究表明,深基坑施工对地铁车站运营会产生影响,但是影响均在安全范围内,施工过程中,应特别做好基坑开挖阶段的监测测量和防护控制措施。In order to better analyze the impact mechanism of deep foundation pit construction on adjacent subway stations and tunnels,a deep foundation pit project in Fuzhou was studied and analyzed.Firstly,sort out the basic situation of the project,the current status of existing stations,and the deep foundation pit support scheme.Based on this,study and analyze the factors that affect the normal operation of surrounding stations.Using the finite element analysis software Midas,a stress simulation analysis of the overall construction process is carried out,and numerical analysis is performed on the structural displacement,internal forces,and clearance convergence of the station.Research has shown that deep foundation pit construction will have an impact on the operation of subway stations,but the impact is within a safe range.During the construction process,special monitoring,measurement,and protective control measures should be taken during the excavation stage of the foundation pit.
