摘　　要：溪洛渡水电站具有"窄河谷、高拱坝、巨泄量"的特点,泄洪建筑物由7个泄洪表孔、8个泄洪深孔以及4条泄洪洞组成。泄洪系统按照"分散泄洪、分区消能"的原则布置。坝身泄洪采用表孔下跌式、深孔上翘式布置,两股水舌在空中碰撞后跌入水垫塘内紊动消能。正常运行方式下,优先开启坝身泄洪深孔,后开启泄洪表孔,泄洪洞宜在坝身泄流能力不足时参与泄洪。Xiluodu Hydropower Station is a hydropower project with narrow valley, high arch dam and huge flood discharge. The flood discharging system of Station consists of seven surface outlets, eight bottom outlets and four spillway tunnels, which are arranged according to the principle of ＂Decentralized flood discharging and zoned energy dissipation＂. The surface outlets are drop-in and the bottom outlets are upturned, and two nappes of surface and bottom outlets will collide in air and then fall into cushion pool for energy dissipation. Under normal operation mode, the bottom outlets are firstly used for flood discharge and then surface outlets, and the spillway tunnels is only used in the condition of outlets＂ discharge capacity being insufficient.
