浸水垭公路滑坡稳定性分析及治理措施

浸水垭滑坡为浅层小型推移式土质滑坡，威胁坡脚公路和居民的安全。根据滑坡的地貌特征、地层岩性、水文特征和坡体特征、边界、规模等，结合现场勘察资料，在对坡体变形特征和成因进行分析的基础上，采用试验、反算和经验相结合的方法，确定主要滑动面的物理力学参数，并分析滑坡未处理前天然、暴雨工况下的稳定性。根据滑坡稳定评价结果，对#1滑坡体4-4’剖面和6-6’剖面采用悬臂式抗滑桩方案治理，对5-5’剖面采用锚索抗滑桩方案治理，同时结合截排水和护面绿化等措施，滑坡变形趋于稳定。

Landslide Stability Analysis of Jinshuiya Highway and Control Measures

The landslide of Jinshuiya Highway is shallow and small soil landslide, which threatens the safety of residents and road. According to geomorphic features, formation lithology, hydrological conditions, structural features, border, scale, etc, of the slope and site investigation results, this paper determines the physical and mechanical parameters of rock-soil in the main sliding zone and analyze the stability under natural and heavy rain conditions before the landslide control by analyzing deformation characteristics and causes in different means, including testing, inverse computation and experience. According to stability assessment results, cantilever type anti-slide piles are used to control 4-4’ section and the 6-6’ section of the landslide #1, anchor cable anti-slide piles are used to control to 5-5’ section, and at the same time such measures as water interception and drain, slope greening, etc., are taken to stabilize the slope.
