排桩支护结构在基坑工程中的应用及数值模拟分析

Application of the Secant Pile Structure in the Deep Excavation and its Numerical Analysis

选取南昌地区某实际工程为研究对象,采用MIDAS GTS4.0大型有限元软件对该工程进行建模分析,得出基坑及支护结构位移;同时还选用理正软件进行计算分析,并将有限元计算结果、理正软件计算结果与实际监测数据进行对比分析,得到一些有价值的结论与规律,为今后类似工程提供一定的参考。

This paper presents the numerical analysis results of using the secant piles as the supporting structure for the deep excavation in Nanchang.The displacements of the supporting structure are predicted by using MIDAS 4.0finite element software as well as Lizheng geotechnical software.The analytical results are compared with the monitored data.
