以上海市某深基坑工程为研究对象，给出了采用“同济启明星”的变形计算结果，采用有限元分析软件 PLAXIS，对基坑开挖过程中重力式围护墙进行变形分析，通过与现场实测结果对比，得出“同济启明星”在重力式围护墙支护结构变形计算中的不足，而 PLAXIS 的模拟结果在趋势上与现场实测结果较吻合，但模拟值数值上较实测值偏小。%Taking some deep foundation pit project as the research object,the paper provides the deformation calculation results by adopting the“Tongji Morning Star”,utilizes the PLAXIS,the finite element software,analyzes the deformation of the gravity enclosure wall in the foundation pit excavation,undertakes the comparison between the analysis and the site examples,and concludes the shortages of the“Tongji Morning Star”in the deformation calculation of the gravity enclosure wall support structure,while the simulation results of PLAXIS is consistent with the site measurement,but the simulated number is smaller than the measured value.
