【摘要】 采用大型有限元分析软件ABAQUS,对软土地区超深基坑的开挖变形性状进行三维非线性有限元分析,并将地连墙水平位移和立柱竖向位移的模拟结果与实际测量数据进行比较,得出了较为一致的规律,并分析了实测值和计算值的异同.更多还原

【Abstract】 Three-dimensional nonlinear finite element analysis was taken by ABAQUS on the deformation of a soft soil ultra deep foundation pit under excavation.The simulated results of horizontal displacements on walls and vertical displacements on columns was compared with site survey.The regularity of these two results was relatively similar and their differences were analyzed.更多还原
