摘要
该文以施工中更改支护设计的某深基坑工程为例,运用PLAXIS 3D软件对深基坑变更设计前后的开挖过程进行了数值模拟,并结合现场监测数据对基坑水平位移和坡顶位移进行了分析。通过对基坑监测数据和数值模拟结果进行对比,发现:PLAXIS 3D有限元软件能够较好地模拟出基坑工程中的各种变形情况,变更后的支护设计满足工程需要,可为其他类似基坑支护设计提供参考。
Based on a deep foundation pit project whose support design was changed during construction,this paper employed the PLAXIS 3 D software to numerically simulate the excavation process before and after the design change of the deep foundation pit,and combined the field monitoring data to analyze the horizontal displacement and slope top displacement of the foundation pit.By comparing and analyzing the foundation pit monitoring data and numerical simulation results,it showed that the PLAXIS 3 D finite element software can well simulate the various deformation conditions in the foundation pit project;and the changed support design meets the engineering demands,which provide reference for the support design of similar foundation pit projects.
