摘　　要：以深圳市翔龙御庭基坑支护工程为背景,运用大型通用有限元ABAQUS对基坑开挖进行了二维有限元数值模拟,通过分析比较有限元数值模拟结果与工程实测结果,验证了ABAQUS有限元软件对支撑桩加承台这种斜抛撑支护形式的数值建模方法和步骤的合理性。Taking the foundation pit support engineering of Xianglongyuting in Shenzhen as the background,large general finite element ABAQUS was adopted to perform two-dimensional finite element numerical modeling on the foundation pit excavation,the finite element numerical simulation results and engineering measured results were analyzed by comparison and the reasonability of ABAQUS finite element software on the numerical modeling method and steps of inclined bracing form（ supporting pile with bearing platform） was verified.
