摘要
针对石壁水库除险加固施工过程中出现的溢洪道左岸高边坡失稳问题,分析论证了不同处理方案。通过对锚索、抗滑桩、坡脚反压以及削坡减载等方案的对比,最终确定了以削坡减载、排水减压处理深层滑动为主,锚杆支护、客土吹附、植被护坡处理浅表层滑动为辅的综合治理方案。对于深层抗滑稳定,根据地形地质条件选取了3个典型断面,通过控制典型断面的稳定性对边坡进行了设计。对于浅表层稳定,根据实际地质情况对植被护坡方法进行了选择,并对满足浅表层抗滑稳定要求的客土厚度进行了计算。工程实际运行情况表明,所采用的综合处理方案是成功的。
According to the instability of high slope on the left bank of Shibi reservoir spillway during construction of danger removal and reinforcement projects, different treatment schemes are demonstrated. By comparison of the schemes of anchorage ca- ble, anti -slide pile, loading on the toe of slope and cutting slope, a comprehensive treatment scheme is adopted, which uses cutting slope and draining as main methods to treat the deep sliding, anchor supporting, replacing the soil on the surface of slide slope and vegetation slope as additional methods to treat the surface sliding. For the deep stability, 3 representative sections are selected according to the landform and geological condition. The slope is designed through controlling the stability of the repre- sentative sections. The slope vegetation ways are selected to reinforce the slope surface, and the thickness of replaced soil is cal- culated so as to meet the demand of stable surface slope.
