摘要
本文分析及阐述了有限元强度折减法的原理和实际应用,以某高层建筑基坑边坡中一支护段为研究对象,采用Midas GTS建立相应的有限元分析模型,运用SRM法(强度折减法)对基坑边坡进行二维数值模拟分析。通过对比基坑边坡在无土钉及岩钉支护和有土钉及岩钉支护情况下的稳定性安全系数、整体位移及最大剪切应变云图,对基坑边坡整体稳定及支护效果作出分析及评价,为类似基坑边坡工程稳定性分析及设计提供参考,具有一定的实用性。
This paper analyzed and elaborated the principle and practical application of Strength Reduction Finite Element Method. Using the method of SRM（Strength Reduction Method） to analyze two dimensional numerical simulation of foundation pit slope, Midas GTS was adopted to establish the corresponding finite element analysis model. By comparing safety factor, overall displacement and maximum shear strain nephogram of the foundation pit slope under the conditions of no support and having the rock and soil nailing support, the analysis and evaluation about the overall stability and support effect of the foundation pit slope were made. The results can provide a reference for similar projects stability analysis and design and have a certain practicality.
