汶川县映秀镇黄家村不稳定斜坡稳定性分析

         

摘要

查明黄家村不稳定斜坡的分布范围、规模、地质条件及诱发因素,采用传递系数法进行稳定性评价和推力计算,得到黄家村不稳定斜坡,整体稳定问题不大,但坡体内部发育的局部灾害体存在稳定问题,主要表现为1号、5号、6号崩滑体和3号崩塌体以及5号、6号崩滑体之间的坡体强变形区,针对坡体中局部发育的不稳定灾害体提出治理主要工程措施。%The transfer factor method was used to carry out stability assessment and thrust calculation after fi nding out distribution scope, size, geological conditions and inducing factors of the Huangjiacun unstable slope. The study results reveal that the Huangjiacun slope is stable as a whole, however some parts inside the slope are considered unstable and potentially disastrous such as the landslide masses No. 1, No. 3, No. 5 No. 6 and the intensively deformed zone between the landslide masses No. 5 and No. 6 in particular. The paper puts forward the major engineering measures to control those unstable and disastrous landslide masses locally developed within the slope.
