溢洪道水流落差的主要部分转化为陡槽末端的动能,即加大了流速。高速水流对下游河床、岸坡或建筑物会造成冲刷破坏作用。为了减小冲刷,维持水利枢纽安全渡讯,必须采取有效的措施来消杀集中下泄水流的余能。
The main part of the spillway water flow translates into kinetic energy at the tip of the chute, which increases the flow rate. High-speed water flow to the downstream riverbed, bank or buildings will cause erosion damage. In order to reduce scouring and maintain the safety crossing of water conservancy hubs, effective measures must be taken to eliminate the residual energy of the centralized discharge of water.
