采用有限元分析软件 Plaxis 对上海市某深基坑工程的围护结构及开挖过程进行数值模拟，计算出围护结构的内力和变形、临近地下管线的位移等结果。对现场监测数据进行了分析，并将计算值与实测值进行相应的对比分析，得到了基坑围护体、土体的水平位移变化规律等结论。结论可用于深基坑的设计优化和变形预测。

In this paper,PLAXIS was used to simulate the enclosure wall and the process of excavation of a deep foundation pit in Shanghai.The internal force,the deformation of the enclosure wall and the underground pipelines nearby were figured out.Through analyzing the on-site monitoring data and comparing with the simu-lating results,the general law of the horizontal displacement of enclosure walls and soil were found.The con-clusions can be used for the design optimization and the deformation prediction of deep foundation pits.
