| 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 satisfying. |
