摘要
依托三峡库区杨家坪Ⅰ号滑坡为例,以地质勘察为主,结合工程类比等手段,确定滑坡稳定性计算的物理力学参数;以Geo-Slope为工具,选取滑坡典型剖面,对其稳定性进行计算,对影响稳定性的降雨历时、滑带强度等因素进行敏感性分析;对滑坡治理措施进行研究,对比两种方案,最后选用了以抗滑桩为主的方案进行治理,取得较好效果。
Relying on Yangjiaping #Ⅰ landslide in Three Gorges reservoir area for example,the physical mechanical parameters for calculation of landslide stability are determined based on geological investigation combined with engineering analogy.A typical profile is selected using Geo-Slope to calculate landslide stability and analyze the sensitivity to influencing factors such as rainfall duration and sliding strength.Landslide control measures are studied finally.Through comparison of the two measures,anti-slide pile is selected as the main control measure of landslide,which achieved good effect.
