摘　　要：结合工程实例,提出并分析了靠近地铁区域的基坑加强处理措施。应用同济启明星FWS软件、二维有限元模拟等对相关实例工程计算,预测基坑开挖时围护桩的变形以及对周边地铁的影响,并通过与实测数据分析,研究相关基坑加强措施的可行性,为类似深基坑工程的设计和施工提供参考。Combined with the engineering example,the strengthening treatment measures for the foundation pit adjacent to the subway area are proposed and analyzed.The related examples of engineering are calculated by Tongji Qimingxing FWS software and 2D finite element simulation,and the deformation of retaining piles during foundation pit excavation and its influence on surrounding subway are predicted.Through the analysis of the measured data,the feasibility of strengthening measures for the relevant foundation pit is studied so as to provide a reference for the design and construction of similar deep foundation pit engineering.
