Abstract
The layout of hydro -complex of Xiangjiaba Hydropower Station is constrained by the topographic condition , the mountain body at left bank should be excavated for the layout of stage II diversion structure , upstream and lower stream approach channels of ship lift.The geological condition of the high slope formed by the excavation is complicated ;in addition, the mined-out area and coal holes exist , which are the main influential factors for the local safety of the slope .To ensure the stability of the high slope and the safety of the hydro -complex, reinforcement measures should be adopted .Through researches, the con-ventional support measures such as anchor cable and anchor rod are taken , and the mined-out area and coal holes are filled . The monitoring after the treatment shows that the high slope is in a stable state .关键词
