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
The finite element program of three-dimensional elasto-plastic was used to simulate the excavation of a practical excavation. The comparison between the calculated data and the measured data verified the feasibility of this program. Through the analysis of the results, this type of The lateral deformation of the maintenance structure and the characteristics of earth pressure during the excavation of the foundation pit supporting engineering are discussed, and some suggestive conclusions are drawn
