摘要
文章以深圳市某地铁车站上盖物业深基坑工程为背景,在基坑开挖前采用Midas有限元软件建立三维模型,分析深基坑施工过程地铁车站及区间隧道的变形发展过程,以及深基坑施工对地铁区间隧道结构变形的不利影响,并通过实测数据验证了采用数值模拟方法确定变形监测重点区域的正确性。
Based on the deep foundation pit engineering of the property on a subway station in Shenzhen, this article used the Midas finite element software to build 3D model before excavation, analyzed the deformation development process of subway station and interval tunnel during deep foundation pit construction, and the adverse influence of deep foundation pit construction on the deformation of subway interval tunnel structure, then, through the actual measurement data, it verified the correctness of using the numerical simulation method to determine the key deformation monitoring area.
