| 摘 要： | 针对合肥市轨道交通l号线及规划2号线中的某车站深基坑,基于有限元Plaxis分析软件,采用硬化土模型,对其进行了分步开挖数值模拟.研究了不同临河距离下深基坑开挖对围护结构和地表变形影响规律,并探讨了临河距离对深基坑两侧非对称变形的影响.研究结果显示:当深基坑临河距离较小时,临河侧地表出现较大隆起变形,另一侧为沉降变形,...

| Abstract: | Aiming at a deep foundation pit for some station of Metro Line 1 and planning Metro Line 2 in He-fei,using hardening-soil model,a numerical simulation on excavation by steps of the deep foundation pit is car-ried out by analysis software Plaxis.The influence of the excavation on the envelop enclosure and the ground de-formation in different over-river distance is studied,and the effect on the unbalanced deformation of the deep foundation pit in different over-river distance are discussed.The analysis result... |
