摘　　要：龙溪水库坝址区水文地质较复杂,强风化破碎岩体、岩溶及断层裂隙共存于库区。为确保岩溶地表成库后具有较高经济效益,结合坝址区工程地质勘察成果,对坝址和坝型适宜性进行详细论证分析。设计优选的坝址为第三坝址,坝型为高填充自密实混凝土重力坝,坝型地质适宜性好、枢纽布置紧凑、开挖及填筑工程量小,方案技术可行且经济,能充分利用水资源。The hydro-geological condition of the site area of Longxi Reservoir is rather complex,with highly weathered and fragmented rock masses,karst and fault fissures coexisting in the reservoir area.To ensure the reservoir is of a high economic benefit after completion,a detailed analysis of the suitability of the dam site and the dam type is conducted based on the geological survey results of the dam site area.After the comparison,the preferred dam site is the third option,and the dam type is a high-filling self-compacting concrete gravity dam.The selected design is of good geological suitability,compact layout,small excavation and filling quantities,technical and economical feasibilities,and full utilization of water resources.
