摘　　要：桂林抽水蓄能电站下水库位于较为对称的V形峡谷河段,两岸山体雄厚。从地形来看,下水库具备建造混凝土坝、当地材料坝的条件。笔者从地形地质条件、施工条件、工程投资等方面对下水库大坝坝址与坝型进行比选研究,通过对上、下坝址与坝型进行比较,确定推荐坝型,以及上、下坝址比选,最终选定下水库下坝址的沥青混凝土心墙坝方案。该研究成果可为类似工程的大坝坝址与坝型比选提供参考。The lower reservoir of Guilin Pumped Storage Power Station is located in a relatively symmetrical V-shaped canyon section with strong mountains on both sides.From the perspective of topography the lower reservoir has the conditions to build concrete dams and local material dams.The authors conduct a comparative study on the dam site and dam type of the lower reservoir dam from the aspects of topographic and geological conditions construction conditions and engineering investment.By comparing the upper and lower dam sites with the dam type the recommended dam type is determined and the upper and lower dam sites are compared.Finally the asphalt concrete core wall dam scheme of the lower reservoir dam site is selected.The research results can provide reference for the comparison and selection of dam site and dam type of similar projects.
