溪洛渡水电站泄洪隧洞的布置及体型设计
Layout and Project Form Design of Xiluodu Hydropower Station Spillway Tunnels
【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18 000~20 000m3/s,占枢纽泄洪的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”型泄洪洞的布置型式。
【Abstract】 In combination with Xiluodu Hydroelectric Project site topographic and geologic conditions and the tunnel flood discharge requirement,for layout,type selection and design of the spillway tunnels,many alternatives have been studied for comparison.Layout type of the spillway tunnels with"pressure tunnel in connection with free flow tunnel"is suggested.
