摘要: 针对一个边坡工程实例,将强度折减理论应用于边坡稳定及加固的弹塑性有限元分析中,分析了边坡加固前后的稳定性并与传统极限平衡法计算结果进行比较.计算结果表明,采用强度折减有限元法不需要任何假设,即可求出边坡的稳定安全系数和滑动面,还能求出抗滑桩桩身弯矩、剪力,为桩身强度验算提供依据,是进行边坡加固前后稳定性评价和进行支挡结构设计的有效方法,能够在工程实际中加以运用.

Abstract: In this paper,An elasto-plastic strength reduction FEM is utilized in the analysis of slope stability and reinforcing and is compared with the equilibrium method. The results show that the strength reduction FEM is can automatically find out the accurate critical slip surfaces and corresponding safety factors. Moreover,it can still find out the glide order of each slip surface under no any hypothesis, and the internal forces of support pile are obtained. It is an effective method for the analysis of slope stability and reinforcing, and it is feasible to engineering application.

Key words: slope, stability analysis, FEM by strength reduction, support pile
