摘要 库区超高边坡开挖坡面高陡,通过定性、定量分析开挖边坡的整体稳定性,结果显示边坡整体稳定,局部结构面与边坡开挖面组合形成的不稳定体需要加强支护,确定支护方案为坡面浅层系统喷锚支护结合局部深层加强支护的联合支护方案,实践证明边坡开挖支护效果良好。 Excavation of the slope is steep and high in reservoir, Through the qualitative and quantitative analysis of the whole stability of excavation slope, The results show that the whole slope is stable, The unstable body formed by combination of local structure plane and slope excavation face needs strengthening support. The support scheme is the combination support of system shotcrete and rock bolt support with shallow depth and local deep reinforcement, Practice has proved that effect of the slope excavation and support is good.
