摘　　要：果多水电站大坝右岸边坡为一斜顺向岩质边坡,开挖后最大高度约170 m,边坡开挖设计采用了避免切脚且尽量减小对边坡扰动的原则来保证其稳定性;在计算方面采用了多方法计算,包括多重网格法、二维刚体极限平衡法和三维刚体极限平衡法,其中三维刚体极限平衡法楔形体计算利用CATIA软件的搜索功能大大提高了计算效率及计算精度,处理措施满足边坡施工期和运行期稳定要求;此外,在施工过程中还对边坡稳定进行了及时跟踪,并采用动态设计的理念,确保了边坡的整体稳定性。The right-bank dam slope of Guoduo Hydropower Station is a dip slope, with its maximum height ofabout 170m after excavation. The principle of avoiding cut foot and minimizing the disturbance to slope is followed in the slope excavation to ensure its stability. Many calculation methods are adopted, including multi-gridmethod, two-dimensional and three-dimensional rigid limit equilibrium method. In the three-dimensional rigidlimit equilibrium method, the search function of CATIA software has greatly improved the computational efficiency and accuracy, and treatment measures meet the stability requirement during construction and operation period.In addition, prompt track and dynamic design are provided to ensure the overall slope stability during construction.
