【摘要】 以上海珠江玫瑰花园基坑为工程原型,采用可考虑土体流变性态的二维施工模拟有限元法,对基坑开挖过程中影响地层移动的主要因素,包括不同的分步开挖工况和不同的支护条件,进行了详细的探讨。获得了坑底和坑周地层移动的规律以及墙后土体水平位移与垂直沉降之间的相关关系,其结论可供工程实践参考。更多还原

【Abstract】 Two-dimensional FEM,which can consider rheology of soil,is used to simulate the construction of excavation. Making use of this method,the rules of ground deformation in the bottom of foundation pit and round it are studied in details for different steps and different supporting conditions during excavation. The correlation between displacements and settlements behind supporting wall is also gained. The results can be used to consult in practice.更多还原
