| Abstract: | A nonlinear finite element model(FEM) has been developed for the analysis of soil-nailed support system.Meanwhile several kinds of constitutive model were chosen for the nonlinearity and inelasticity of soil,and the Goodman element was adopted for the soil-nail interface.The staged excavation and retaining can also be stimulated by this model.An engineering case is analyzed as an example,and the result are satisfactory. |
