摘要
针对路基边坡尤其是高填路基边坡的稳定性问题,基于强度折减法,采用Flac/3D计算分析软件对不同工况条件下的路基边坡稳定进行了分析,讨论了不同路基高度、路基填料性能指标、边坡坡率等因素对路堤安全系数的影响,并与传统极限平衡理论分析方法计算结果进行了对比分析。
According to the characteristics of subgrade slope, especially the high fill subgrade of based on the strength reduction method,the slope stability of embankment under different conditions is analyzed by Flac/3D software. Factors which affect the slope stability,such as the embankment height,the strength index of fills,and the angle of slope are systematically analyzed, and the calculation results of strength reduction method are also compared with the calculated results of limit equilibrium method.
