中文摘要：

以安化县某边坡为例,通过对边坡的勘察资料的分析及实地工况的选择,建立了边坡三维模型,采用Mohr-Coulomb准则同时基于强度折减法的思想对此边坡进行了稳定性分析,得出计算结果,并且将计算结果与极限平衡法计算结果比较,表明采用强度折减法思想的FLAC3D软件建模的稳定性计算简单可行,为滑坡病灾防治提供可靠依据。

英文摘要：

This paper presents the slope stability analysis results of a potentially instable slopes in Anhua County.The three dimensional finite analysis model was established throughout the geotechnical investigation results and site specific topographies.The Mohr-Coulomb failure criteria and the strength reduction method were used in the analytical model.The numerical results are compared with the results from the limit equilibrium method and it is concluded that the strength reduction can be used in FLAC3 Danalysis.
