针对地铁周边基坑工程特点,采用三维有限元方法建立计算模型,对地铁结构变形进行了预测分析,同时设计了地铁保护监测方案,将理论分析与实测数据进行对比分析。对地铁周边基坑工程施工的地铁保护措施提出了合理化的技术对策和方法建议。
According to the engineering characteristics of the foundation pit around the subway, a three-dimensional finite element method was used to establish a calculation model to predict the deformation of the metro structure. At the same time, a metro protection monitoring scheme was designed, and the theoretical analysis and the measured data were compared. Put forward reasonable technical countermeasures and methods to the metro protection measures for the construction of foundation pit around the subway.
