深基坑开挖施工有限元分析

Finite Element Analysis on Deep Foundation Excavation

利用所编制的三维弹塑性有限元程序对某实际基坑开挖进行了模拟,通过计算数据与实测数据的比较,验证了本程序的可行性。并通过对结果的分析,对此种类型的基坑支护工程开挖过程中维护结构的侧向变形、土压力的特征进行了探讨,得出了几点建议性结论。

Simulating of an actual foundation excavation with three-dimensional elastic-plastic finite element is conducted according to the comparing results between the computing data and the field testing data,it has been testified that the proceeding is feasible on the basis of the analysis for the results,characteristics of the supporting structure's horizontal displacements and the earth pressure for foundation excavation have been studied,and some suggestive conclusion have been drawn.
