摘要：

By　using　the　trial　stress　return　mapping　algorithm,　a　user-defined　material　subroutine　(UMAT)　of　the　constitutive　model　of　soil　considering　complex　stress　path　is　complied.　The　precision　of　the　UMAT　is　tested　by　simulating　triaxial　compression　tests　and　triaxial　extension　tests　based　on　ABAQUS.　Three-dimensional　finite　element　analysis　of　excavating　small　diameter　axisymmetric　round　foundation　is　carried　out　by　means　of　the　second-developed　ABAQUS　with　the　UMAT.　The　variations　of　the　intermediate　principal　stress　and　the　minimum　principal　stress　and　the　laws　of　soil　arch　caused　by　the　intermediate　principal　stress　under　the　plane　strain　condition　are　studied.
