摘　　要：狮溪水库坝址区为高山峡谷区,是一座具有灌溉和供水功能的综合性水库。现场踏勘后综合考虑地形条件、施工条件以及工程投资等因素,通过多方案设计与分析,确定采用取水洞、放空洞以及导流洞"三洞合一"的布置方案。该优化设计解决了三条隧洞同岸布置,施工过程中相互影响的难题,同时缩短了施工工期,节省了工程投资,对类似工程具有借鉴。The dam site of Shixi Reservoir is located at high mountain gorge area,which is a comprehensive reservoir with irrigation and water supply functions.After site investigating,considering comprehensively the topographical conditions,the construction condition and the project investment and so on factors,through carrying out designing and analyzing many schemes,determined and adopted the "three tunnels in one" layout scheme,namely taking one tunnel as three tunnels including the intake tunnel,diversion tunnel and emptying tunnel.By means of the optimization design,the difficult problem about mutual interference resulting from at the same side laying three tunnels during the construction was solved,meanwhile the construction investment was saved,and the construction period was shortened.The design is also of reference significance to other simi-lar projects.
