摘　　要：溢洪道的控制堰下一般接陡坡泄槽,为使陡槽内水流平顺,平面上陡槽以等宽直线布置为佳,但受地形、地质等条件的限制,会采用急流段边墙转折,这就将导致冲击波的产生.消波墩作为陡槽局部抬高的变体,可以有效的克服产生的急流冲击波,有良好的工程应用效果.The steep channel is often behind the control wier of spillway. In order to make the current of steep channel surgeless, steep channels is designed to be straight stretch and equal in width in plane. But the turn of abutment wall in the cataract is adopted by the limit of geomorphy or geology condition. So the blast wave come into being. The wave breaking pier is the version of locally lifting steep channel. It can eliminate the chute blast wave and has a good effect.
