摘　　要：为研究多诺水电站右岸倾倒变形体边坡的演化过程,结合地质资料和监测数据来分析边坡变形影响因素,通过底摩擦模型试验模拟倾倒变形体初始形成过程,最后综合得出库水位升降下多诺水电站右岸倾倒变形体边坡的变形机制和演化过程。结果得出:(1)受坡体结构的控制,边坡在河谷下切阶段容易出现倾倒现象;(2)水库蓄水加速了水位变动区的岩体蠕滑变形;(3)地震致使岩体劣化,进而加速了蓄水作用对边坡变形的影响;(4)倾倒变形体边坡的变形影响因素主要有:卸荷作用、蓄水作用和地震作用。To study the evolution process of the deformation slope on the right bank of the Dono hydropower station, combining with geological data and monitoring data to analyze the influencing factors of slope deformation, simulate the initial formation process, and finally conclude the deformation mechanism and evolution process of the deformation slope. The results are:(1) under the control of the slope structure, the slope falls;(2) the reservoir storage accelerates the creep deformation in the water level change area;(3) the earthquake causes the deterioration of the roc.
