介绍了钦崇高速某顺层边坡滑坡治理工程中已查明的滑坡区工程地质条件,滑动面、滑动带的位置,通过对现场工程地质条件的系统调查,分析评价了该滑坡体的成因及稳定性现状;根据钻孔资料提供的岩土体和滑面的参数,并结合参数的反算,得到了滑面的c、值,最后计算得到非正常工况下(暴雨)的滑坡稳定安全系数为0.91,说明当遇到长时间暴雨时,滑坡会进一步发展,需要及时治理。根据对该边坡的地质模型分析和对其进行的定量力学评价,提出了相应的治理设计措施。
介紹瞭欽崇高速某順層邊坡滑坡治理工程中已查明的滑坡區工程地質條件,滑動麵、滑動帶的位置,通過對現場工程地質條件的繫統調查,分析評價瞭該滑坡體的成因及穩定性現狀;根據鑽孔資料提供的巖土體和滑麵的參數,併結閤參數的反算,得到瞭滑麵的c、值,最後計算得到非正常工況下(暴雨)的滑坡穩定安全繫數為0.91,說明噹遇到長時間暴雨時,滑坡會進一步髮展,需要及時治理。根據對該邊坡的地質模型分析和對其進行的定量力學評價,提齣瞭相應的治理設計措施。

This article introduces engineering geological conditions, landslide mass structure, slip surface, and sliding zone in the process of landslide governing of a bedding slope in Qinzhou-Chongzuo highway, based on the site survey of engineering geological environmental condition, and then analyzes and evaluates causes and stability status of the landslide mass. According to the rock mass and sliding surface parameters of the borehole data, and combined with inverse computation of parameters, we get the sliding surface c and φ value. The safety factor of the landslide is 0.91 under the abnormal condition (rainstorm) , which shows that when faced with a long heavy rain, the landslide further develops, and needs timely treatment. According to the geological model analysis and quantitative mechanical evaluation, we finally propose corresponding preventive measures.
