摘　　要：梨园水电站地处金沙江中游,坝址区两岸分布有多个大规模不同成因类型的堆积体,通过对堆积体开展勘察、试验、研究,因地制宜充分利用其为坝体基础和坝料,降低工程造价;同时对坝体变形控制、面板接缝止水、面板裂缝控制等进行研究并运用,减小了坝体沉降变形量、渗漏量,提高了面板接缝止水安全性,面板裂缝得到有效控制,取得良好效果,且经济效益显著。Liyuan hydropower station is located in the middle reaches of Jinsha River.There are many large-scale landslide masses of different types distributed on both banks of the dam site area.Through investigation,test and research on the landslide mass,we can make full use of them as dam foundation and dam materials according to local conditions,which can reduce the project cost;At the same time,the dam deformation control,waterstop and joint,crack control of face slab are studied and applied,which reduces the settlement deformation and leakage of the dam,improves the waterstop an joint safety,controls the face slabs crack effectively,achieves good results and remarkable economic benefits.
