摘　　要：溪洛渡水电站的泄洪设施由坝身孔口和两岸泄洪洞组成，其中隧洞泄洪流量达１８０００～２００００ｍ３／ｓ，占枢纽总泄洪量的４５％左右。本文结合坝址地形、地质条件及隧洞泄洪要求，对泄洪洞的布置、选型与设计开展了多方案的比较研究，提出了“有压接无压—洞内龙落尾”的泄洪洞布置型式。The flood relief facilities of Xiluodu Hydroelectric Plant consist of dam outlets and flood relief tunnels in both banks,in which the flood relief discharge through tunnels amounts to 18,000～20,000 m 3/s,making up some 45% of total facilities' discharge.In combination with dam site topography,geologic condition and tunnel flood relief requirement,the multi alternative comparison research is earried out for flood relief tunnel layout,type selection and design,and the flood relief tunnel layout of “pressure to no pressure water drop in tunnel” type presented.
