| 摘 要： | 研究目的:为了再现夏呀河滑坡滑动过程及其形成,对夏呀河滑坡进行三维地质模拟计算分析并与采用基于蒙特卡罗法的多级黄土滑坡可靠性分析结果进行对比研究.研究结论:研究结果表明:天然状态下,模拟计算的1、2、3、4级滑面的安全系数分别为1.27、1.30、1.56和1.73,说明在给定的滑动面空间形态和天然状态各岩土力学参数条件下,4个滑面都不会出现失稳现象；当岩土参数按照饱和状态参数模拟计算的1、2、3、4级滑面的安全系数分别为0.96、1.15、1.48和1.60,若将安全系数fs=1.2作为临界值,则在饱和状态下,1级滑面出现明显的失稳现象,2级滑面安全系数为1.15,处在失稳的边缘,3、4级滑面安全系数大于1.2,处于稳定状态.与采用基于蒙特卡罗法的多级黄土滑坡可靠性分析的结果基本一致. |

| Abstract: | Research purposes: In order to reproduce the processes and the formation of Xiayahe landslide,the 3D geological simulation analysis for Xiayahe landslide was made and the simulation result was compared to the analysis result of the stability of the multiple-stage landslide in loess area with the Monte-Carlo simulating method. Research conclusions: The research results showed that: in natural state,the simulated safety factors of the sliding surface of the 1,2,3 and 4 stages were respectively 1.27,1.30,1.56 ... |
