摘　　要：采用ABAQUS通用有限元软件对粉煤灰路堤边坡稳定性进行研究,采用强度折减系数法的方法进行计算,通过对实际工况路堤边坡稳定性和变形的分析,并且与特征部位变形曲线结果进行对比,发现强度折减系数法模型的精度较高,能够满足工程仿真试验的要求。本文研究可作为进一步对以碎石粉煤灰为填料的路堤边坡稳定性分析的基础。With the Abaqus general finite element software to study the stability of fly ash embankment slope, uses the method of strength reduction coefficient to calculate, through the analysis of the stability and deformation of the embankment slope in the actual working condition, and compared with the deformation curve result of the characteristic part, it is found that the strength reduction coefficient method model can meet the requirements of engineering simulation experiment. This paper provides the basis on the stability analysis of embankment slope with crushed stone fly ash as filler.
