摘要
P．K堰顶部宽而底部窄,有效增加了堰的展长,增加了泄流能力,尤其适用于现有溢流坝的改造。模型试验表明。P．K堰的泄流能力远大于直线堰,B型P．K堰的泄流能力高于A型。
A new labyrinth weir called P.K weir with the larger top and narrow bottom can increase weir＇s developed lengths and discharging, especially be suitable for modification of overflow dams. The resuhs of hydraulic model test show that discharge capacity of P.K weir is larger than straight-line crest weir and the discharge capacity of model B is larger than model A.
