摘　　要：龙首二级水电站的泄水建筑物为岸边陡槽溢洪道和泄洪冲沙洞。泄水建筑物单宽流量大、水头高、流速大,并且下游消能区自然条件较差,高速水流的流态控制和消能防冲问题突出。本文介绍泄水建筑物布置方案及消能防冲问题的试验研究成果。Escape works of Longshou Secondary project are composed of bank-run spillway and spillway-flushing tunnel. The discharge per unit width, head and velocity are big and natural condition at downstream energy dissipation area is poor. Problems of fluid state control of high-velocity flow and energy dissipation are prominent. In this paper, experimental result on the escape works layout and downstream energy dissipation are presented.
