摘要
结合上海某具体工程实例,采用基于土体硬化模型的三维有限元方法分析了深基坑开挖围护结构的变形以及对邻近建筑物的影响。计算结果与工程实测进行了比较,结果表明:采用的计算模型是合理的,该方法适用于敏感环境条件下深基坑变形分析。
The design and practice of a deep excavation in Shanghai was presented. The 3D FEM based on Hardening Soil （ H - S ） Model was adopted to analyze the deformation of the excavation and its effect on adjacent buildings. The results show that this method gives good prediction of both the deformation of the soil retaining structures and the settlement of the soils behind the wall after eomparing the results with measured data. Meanwhile, the method is suitable to deformation analysis of deep excavation under sensitive environment circumstance.
