金山水电站右岸山体变形分析及加固设计

金山水电站在右岸山体在基坑开挖过程中，右岸山体发生变形，经分析认为右岸山体顺坡卸荷裂隙、山体本身存在的F8及F13断层组合体及雨水的渗入是使山体发生变形的主要原因，工程处理措施采用削坡减载、建立山坡截排水系统、F13断层局部置换及表面封堵、延长并加深右岸帷幕及局部锚杆支护处理，右岸山体变形最终趋于稳定。

Study on the Mountain Deformation on the Right Bank of Jinshan Hydropower Station and Its Reinforcement Design

Mountain deformation on the right bank of Jinshan hydropower station occurred during the excavation of foundation pit.The study found that the mountain deformation is resulted from the unloading fissures on the positive slope, the existence of composite faults of F 8 and F 13 , as well as rain seepage. Measurements are taken to stabilize the mountain, such as reducing slope, setting up cutoff and drainage system on the slope, partial replacement and surface covering of the faults with concrete, extending and deepening the curtain at the right bank, together with anchor bar supporting. Mountain deformation turned stable finally.
