摘　　要：以分析深基坑支护理论为基础,概述了常用的几种计算基坑受力与变形的方法和有限元理论,以石家庄市某工程为例,将深基坑的支护与开挖简化为平面应变问题进行了FLAC软件数值模拟计算,根据计算结果,分析了支护结构的受力和变形规律,并通过调整桩长作了进一步计算,以分析桩长对支护结构变形的影响,得出合理的模拟结果,验证了有限元模拟的合理性。Based on the analysis of deep foundation pit support theory, summarizing the several methods of calculating pit stress and transformation, finite element theory. Taking a pit in Shijiazhuang for example, the support and excavation of pit boil down to plane strain problems, so as to carry on FLAC software numerical simulation computation. According to the results, analyse the supporting structure stress and deformation law and adjust the length of pile to the further calculate, analyzing the length of pile effect to the supporting structure transformation. Getting the reasonable simulated result, in order to check the rationality of finite element simulation.
