摘要： 某圆形深基坑工程为例，借助三维有限差分软件FLAC\+\{3D\}对深基坑工程的施工过程进行了数值模拟，模拟过程中考虑了潜水、承压水以及基坑降水和土体变形耦合作用，最后将数值模拟结果和实际监测值进行了对比分析。

Abstract: Taking Tongli elevator (Kunshan) circular deep excavation as an example, this paper presents the numerical simulation results using threedimensional finite difference software FLAC3D on the construction process of a deep excavation. The simulation considered the influence of both unconfined and confined groundwater, the coupling effect of dewatering on the deformation of the soil mass. The analytical results are compared with the observed data.
