提高溢流堰溢流能力的研究

Study on Increasing Spilling Capacity of Spillweir

将溢流堰的轴线布置成拆线或曲线，称为锯齿堰或迷宫堰．它与传统的直线堰相比，其溢流能力可提高数倍，因而特别适用于地形受到限制的狭谷形地区无闸控制溢洪道，这种堰不仅泄水效率高，总造价也较低，因此，它是一种应用前景较好的堰型。

When the Conventional weir is modified into saw tooth line or labyrinth weir, thespilling capacily can be increased several times. There fore the folded or labyrinth weir is especial-ly suitable the non-gate spillway in the vassey area where the spilling ability is restricted. It is anhopeful weir type due to the high spilling efficiency and low cost in certain condition
