| 中文摘要: |
| 建立土钉支护的非线性有限元模型,土体本构采用Mohr-Coulomb模型,土钉之间采用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. |
| 英文摘要: |
| 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. |
