摘要
采用FLAC^(3D)软件,建立路基边坡三维数值模型,基于强度折减法对边坡的稳定性进行数值模拟,研究土的黏聚力和内摩擦角对路基边坡稳定性影响。研究结果表明:随着黏聚力或内摩擦角的增加,路基边坡安全系数均线性增加,塑性变形区域逐渐减小。
FLAC^3D is used to establish three-dimensional numerical model of subgrade slope. Based on strengthreduction technique, the influence of cohesive force and angle of internal friction of soil on subgrade slopestability is studied. The research results show that, along with the increase of the cohesive force or internal frictionangle, the subgrade slope safety factor increases linearly, plastic deformation area decreases gradually.
