摘　　要：结合弥勒县虹溪排洪隧洞出口泄槽Ⅱ段需设弯道而产生急流冲击波的特点,通过对急流弯道中冲击波的形成分析计算,对排洪隧洞出口泄槽弯道上产生急流冲击波采取了相应的工程措施,保证了隧洞出口泄槽水流的平顺连接。虹溪排洪隧洞工程2007年运行至今,弯道运行较好,水流平顺流畅。The paper deals with the necessary engineering measures for handling of the impact waves caused by the torrent in the bend of the chute at the flood release tunnel outlet,which were taken after analysis and calculation of the torrent impact waves produced in the torrent bend according to the features of the torrent impact waves caused by provision of a bend at the chute section II of the Hongxi flood release tunnel outlet in Mile County.The engineering measures ensure the smooth connection of the water fl ow of the chute at the tunnel outlet.The Hongxi fl ood release tunnel has been under operation since2007,the bend has been under proper operation and its water fl ow has been easy and smooth.
