Secondly , safety factor of a landslide body with a polygonal sliding surface is analyzed in this paper . the results demonstrate that this method can consider that the different material stiffness parameters in the landslide body have an effect on the safety factor . finally , the safety factor of a three - dimension landslide body with a spherical sliding surface is calculated with this method , and the applicability of this method for three - dimension slope is verified after comparing the result with theoretical answer
文中首先用具有理论解的算例? ?垂直坡受集中荷载的安全系数问题验证了该方法的正确性，再通过对一个具有折线滑动面的滑坡体的安全系数的分析说明了该方法还可以考虑塌滑体内不同的材料刚度参数对安全系数的影响，之后用该方法对一个具有球形滑裂面的三维滑坡体进行了计算，通过与闭合解的比较验证了该方法对三维边坡问题的适用性。
