［摘要］通过太原市某一深基坑工程实例，介绍了基坑支护方案的分析与选取。在充分考虑场地和建设要求的条件下，采用桩锚支护作为该深基坑的支护方案。先通过理正深基坑软件对该支护方案进行设计，再运用FLAC3D数值差分软件对该支护设计进行验证及内力位移分析。本设计理念可供同类基坑工程参考和借鉴。

Abstract: Through an example of a deep foundation pit in Taiyuan, the analysis and selection of the foundation pit supporting method is introduced. Under the condition of fully considering the site and construction requirements, using the pile anchor supporting was used as the deep foundation pit support method. The first thing is to design the supporting method of deep foundation pit by Lizheng, then using FLAC3D finine difference software to validate the supporting design and internal force displacement analysis. This design idea can be used for reference for similar foundation pit engineering.
