【摘要】 用SnEpFem土钉墙有限元数值分析系统,对土钉支护结构进行变形与破坏的数值模拟分析,对土钉支护结构的可靠性进行合理评价。此系统可对坡面水平位移、坡顶沉降及沉降范围、坑底隆起、张拉区和塑性区的作用机制进行全面分析,也可模拟施工中每一步开挖过程并给出坡体的变形与破坏情况。通过对某基坑土钉支护结构的工程实例数值模拟分析,计算得到的坡面最大变形与实际监测的变形数据相比较,二者相差很小,充分证明了SnDpFem土钉墙有限元分析系统的可靠性。更多还原

【Abstract】 The deformation and destruction of soil nail support structure were analyzed with value analogy,and the reliability of soil nail support structure was evaluated,by SnEpFem Soil Nail Wall Finite Element Value Analysis System.The system can completely analyze horizontal displacement of slope surface,subsidence of slope top and subsidence range dimension,pit bottom hooving-up,and reaction mechanisms of tension area and plasticity area.The system also can simulate the deformation and destruction of slope body which occurred in each step during construction.The comparison of deformation data between calculation and actually monitoring shown that the difference is small.That proved the reliability of SnEpFem Soil Nail Wall Finite Element Value Analysis System.更多还原
