摘要
建立土钉支护的非线性有限元模型,土体本构采用多种本构模型,钉土之间采用Goodman单元模拟,能够模拟基坑的开挖与支护的施工过程。对某一具体基坑工程进行了模拟计算,取得了较满意的结果。
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.
