摘　　要：古贤水利枢纽泄水建筑物是典型的高水头、高流速、大流量泄洪工程,在右岸地面厂房方案中,由于地形限制,电站厂房距泄洪排沙洞出口挑坎位置最近仅约100 m,厂房受挑流雾化影响严重,为减轻或避免雾化影响,设计方案中出口消能方式宜考虑底流消能。The release structure of Guxian hydro-complex is a typical example of high head, high velocity and big discharge capacity. Due to terrain restriction, the proposed ground powerhouse on the right bank may be seriously affected by ski-jump atomization for the reason that the shortest distance between the powerhouse and the jet bucket is about 100m only. Therefore, the energy dissipation by underflow is recommended in the optimization design so as to minimize the effect of flood discharging atomization.
