摘要
以双折线滑动面边坡为例,将FLAC3D软件作为数值计算工具,采用基于强度折减法的数值计算方法计算了不同滑动面几何形态下的边坡稳定安全系数,并与刚体极限平衡法的计算结果进行了比较。结果表明,滑动面上折线倾角和下折线倾角的变化对安全系数影响较大,而滑动面上折线高度的变化对安全系数的影响不太明显。
A slope with double sliding surface is chosen to investigate the influence of the different geometry of the sliding surface on the safety factor with the FLAC3D software. The strength reduction method is used to calculate the safety factor of slope stability. And then some comparative analysis is implemented with the result obtained by the rigid body limit equilibrium method. The results show that the dipping angle of the sliding surface has great influence on the safety factor, while the height of the sliding surface gives no obvious influence on the safety factor.
