摘　　要：三里坪水电站右岸420道路高边坡岩体为白云质灰岩及白云岩等碳酸盐岩,岩层陡倾,节理裂隙发育,溶沟溶缝多,为查清该边坡开挖后的稳定性,在充分考虑边坡走向、裂隙切割以及岩溶等对边坡稳定性的不利影响后,并结合该工程地质条件及裂隙组合特征,进行了分段破坏模式预测和稳定分析,提出合理的开挖坡比和加固处理措施。The rock mass of high side-slope by No.420 Road on the right bank of Sanliping Hydropower Station belongs to carbonate rock with steep strata,developed joint fissure and dissolution groove-fissure.In order to determine the stability of the high-side slope after excavation,through fully consideration of the unfavorable influence of the slope trend,fissure cut and karst etc.and in the combination with the characteristics of engineering geological condition and fissure composition,the sectional damage mode and stability analysis are conducted and excavation slope,treatment measures are put forward.
