摘要
结合实际,运用有限元分析软件ANSYS对基坑开挖进行非线性数值模拟,得到每步开挖时基坑支护变形、基坑沉降量、周边建筑位移等情况。通过对凤台金汇广场基坑支护实例进行分析,将数值模拟的结果与现场实测的情况进行对比,得出该方法在基坑开挖中有很强的实用性。对判断类似设计方案的合理性具有一定的指导意义。
Combination with the actual, using the finite element analysis software ANSYS to nonlinear numerical simulation of excavation, get each step excavation deformation of foundation pit supporting, the displacement of foundation pit and surrounding buildings settlement, and so on. By Feng Tai Jin Hui square of Feng Tai, contrast the results of numerical simulation with field measurement results, foundation pit supporting examples analysis, it is concluded that the method in foundation pit excavation has strong practicality. To judge the rationality of the similar design has a certain guiding significance.
