复合土钉墙变形性能的三维弹塑性ADINA有限元分析
Three-Dimensional Elastc-Plastic ADINA Finite Element Analysis of Deformation of Composite Soil Nailed Wall
摘要
Abstract
Based on the nonlinear finite element software ADINA, the construction process of excavation and supporting of the composite soil nailed wall of soil nailing and cement-soil piles for deep foundation excavation is simulated by a whole three-dimensional finite element model.Spatial action of foundation pit was considered in the model.The deficiencies of two-dimensional plane model or a partial spatial one were overcomed.Whole displacement of foundation, the horizontal displacement of excavation face, the subsidence displacement of the ground beside the foundation pit and the bottom heave displacement are obtained, which were compared with the actual measured data.The results show that the finite element analytical results are in agreemennt with those of the field test data.The good agreement shows that the finite element model and analytical method are reliable.The results can satisfy the need of engineering and can be well applied to analyze and predict practical engineering.关键词
