摘　　要：介绍了在引水式小水电站压力前池宽度不变的情况下，采用曲线形布置溢流堰的情况。由于加长溢流堰长度，可以有效地增大溢流堰的泄流能力。从而减小了因机组弃荷溢流而导致引水建筑物规模扩大的弊端；达到降低工程造价的目的。In the paper, a curved layout overflow weir adopted in the forbay of a small diversion style weter power station in recommended, Through model experiment,it is proved that the curved layout weir adopted, by lenghthening the overflow weir, can effectively increase the flowing capacity, and reducethe abuses due to the abandoning of water loading of the generating units.
