摘要: 以某露天矿山高陡边坡为研究对象,基于工程地质条件,提出了“削坡减载”的高陡 边坡恢复治理方案,分别对矿山A 区和B 区内的高陡边坡进行削坡设计。基于极限平衡法,分别 对削坡后的边坡安全性进行了计算。结果表明,在自重和地震作用下,A 区和B 区削坡后的边坡 安全系数分别为1.753 和2.301,均大于边坡最小安全系数。

Abstract: Taking the high and steep slope of an open-pit mine as the research object,based on the engineering geological conditions,the restoration and treatment scheme of the high and steep slope with "cutting slope and reducing load" is proposed,and the slope cutting design of the high and steep slopes in Area A and Area B is carried out respectively. Based on the limit equilibrium method,the slope safety after slope cutting is calculated respectively. The results show that under the action of self-weight and earth⁃ quake,the safety factors of slope after slope cutting in Area A and Area B are 1.753 and 2.301 respective⁃ ly,which are greater than the minimum safety factor of slope.

Key words: high and steep slope, slope restoration and treatment, cutting slope and reducing load
