摘　　要：运用FLAC3D和理正数值模拟软件对实际深基坑桩锚支护结构进行了数值分析与计算.主要分析了开挖过程中支护桩桩顶位移、深层水平位移及支护桩内力的变化,并将现场实测值与模拟软件的计算结果进行了对比分析.结果表明,FLAC3D数值模拟结果更符合实测值,可为基坑工程的设计和施工提供参考.Two simulation softwares of FLAC3D and LIZHENG are applied to calculate and analyze the actual pile-anchor supporting structure of the deep foundation pit. This research mainly focus on the pile top displacement of supporting piles, the deep horizontal displacement and internal forces in the excavation process. Furthermore, field-measured values and the calculation results by simulation softwares are compared and analyzed. The results prove that the FLAC3D simulation value is more in line with the site measuring. This can provide a reference for the design and construction of the foundation pit project.
