摘　　要：古瓦水电站为钢筋混凝土面板堆石坝,坝区地处向斜的核部,两岸边坡类型为层状同向结构边坡。岩石为厚层状变质砂岩夹板岩,倾坡外的层面对边坡稳定不利,边坡稳定性较差。通过对坝区边坡破坏模式研究,综合分析确定边坡稳定计算边界和结构面参数,对坝区边坡稳定进行计算复核,优化边坡支护设计。通过对坝区特殊地质条件下边坡稳定计算的介绍,为相似工程边坡支护设计提供借鉴经验。Guwa Hydropower Station is a reinforced CFRD. The dam site is located in the core of syncline, and the slope types on both sides of the bank are layered and synthetic slopes. The rocks are thick layered metamorphic sandstone splints, and the layers outside the slope are not conducive to the stability of the slope, and the stability of the slope is poor. Through the study of the slope failure mode, the calculation boundary and structural plane parameters of the slope stability are determined by comprehensive analysis, and the stability of the slope is calculated and checked to optimize the slope support design. By introducing the calculation of slope stability under special geological conditions at dam site, this paper provides reference experience for slope support design of similar projects.
