| 摘 要： | 本文从工程实践需要和目前基坑工程的研究现状出发,研制了能考虑基坑开挖的空间效应、土与围护结构的相互作用及施工过程的基坑工程三维有限元分析程序,研究了基坑开挖过程中围护结构变形、主动土压力、支撑轴力、基坑周围地表沉降量及底部隆起的空间分布,探讨了基坑周围地表沉降量分布形式。最后与杭州市某基坑工程实例进行了对比分析,验证了基坑工程进行三维分析的必要性以及计算模式的合理性。

| Abstract: | Based on the needs of engineering pra ctice and the present research on excavation,a 3-D FEM program for excavation engineering has been dev eloped,in which the spatial effect o f the pit during excavation,the soil-retaining structure interaction and the proce ss of construction are taken into account.And the study of deformation of retaining structure during excavating ,activ e earth pressure,brace force,distr ibution type of ground settlement an d basal heave of excavation are analyzed by the pro gram.Lastly,an excavation case in Hangzhou has been studied,and the necessity of 3-D analysis and the reasonableness of calculating model have been verified. |
