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,给坝址选择、枢纽布置及方案选择带来很大困难。通过加强地质勘探工作、查明枢纽区地质条件,对枢纽布置进行7个方案的研究及技术经济比较,最终选择了适合工程地形地质特点、技术可行、经济较优的混凝土面板堆石坝、右岸溢洪道、左岸坝后地面厂房枢纽布置方案。Liyuan Hydropower Station locates in the middle reaches of Jinsha River. It is difficult for dam site selection and project general layout due to several large-scaled geological accumulation bodies with different developmental reasons distributed in dam area. Based on geological exploration data and analyses, seven project layout schemes are proposed and compared with technical and economic methods. The optimal layout scheme of concrete face rockfill dam, right-bank spillway and left-bank surface powerhouse at dam toe is finally selected, which is best adapt to the geological features of dam site, feasible in technology and less in project investment.
