摘　　要：引入空间桩单元和空间曲梁单元,把深基坑支护结构中的环梁支护结构体系假设为带桩和环梁的空间框架。建立了简化的三维杆系有限元模型,并编制了相应的计算程序。工程实例的计算结果表明,本文提出的计算方法较为合理,具有一定的理论及工程应用意义。Ring beam retaining structure was supposed as space frame structure with pile and ring beam by introducing the 3D pile element and the 3D curved beam element. Based on the supposition, a 3D finite element analysis model was proposed and a program was developed to compute the structure in this style. The computation and analysis of practical engineering case show that the present method is rational and valuable in theory and practice.
