中文摘要: 采用定性和定量相结合的方式对乌石头山滑坡进行了研究。研究结果表明:乌石头山滑坡为小型牵引式土质滑坡,滑坡的产生主要与滑坡体的岩土体性质、滑坡处的地质环境条件(地形、地貌、降雨)及人工活动有关。对滑坡进行定量计算分析可知:自重工况下,坡体稳定系数1.44(>1.15),处于较为稳定状态;自重+暴雨工况下,坡体稳定系数1.03(<1.15),处于欠稳定状态,极端条件下坡体可能再次发生滑坡。
Abstract:In this paper, the method of combining qualitative and quantitative analysis was utilized to study the Wushitoushan landslide. The results indicated that the formation of Wushitoushan landslide was a small tug-type soil landslide, the inducement of landslide was mainly related to the rock and soil properties of the landslide body, the geological environment conditions of the landslide (topography, landform, rainfall) and human activities. According to the quantitative calculation and analysis of the landslide, under the condition of dead weight, the slope stability coefficient was 1.44 (> 1.15), in a relatively stable state; while the slope stability coefficient was 1.03 (< 1.15), s in an unstable state, and slope landslide may occur again under extreme conditions.
