| 摘 要： | 对上海铁路南站特长平行相邻基坑开挖进行有限元计算并对工程监测分析.相邻基坑施工变形影响明显存在.邻近距离越小,变形影响越大.同时开挖方式的变形影响“相对公平”.变形影响与基坑开挖面成正比.土体加固对控制变形影响有明显作用.围护壁或支撑的刚度变化仅使变形绝对值大小发生变化,而变形影响依然存在.

| Abstract: | Excavation of adjacent pits in Shanghai South Railway Station is studied by means of FEM method and in-site measurement.Displacement transformation of the adjacent pits exists obviously.The closer are the adjacent pits,the more is the displacement transformation.The displacement transformation of pits by means of simultaneous excavation is relatively fair.The displacement transformation is in direct proportion to the excavation width.Reinforcement to mud has a nice influence on the displacement transformation.Changing rigidity of retaining wall or supporting system can only change the absolute displacement,but the displacement transformation doesn't disappear. |
