摘要
在山区峡谷中修建水利枢纽工程,能获得较大的发电效益,但同时也阻断了流域内洄游性鱼类的生态路线,对流域内鱼类生态造成较大的影响。本文以新疆北疆伊犁河流域内拦河枢纽工程为背景,采用不同侧垂直竖缝式鱼道进行水力特性实验研究,对不同工况下鱼道竖缝处流速和水深进行了研究分析,结果表明在不同水位工况下,鱼道内的流速保持在恒定状态下,满足鱼类洄游条件。
The construction of hydro-junction projects in mountain canyons can achieve greater power generation benefits,but at the same time, it also blocks the ecological route of migratory fish in the basin,which has a great impact on the fish ecology in the basin.In this paper,based on the project of the Ili River Basin in northern Xinjiang,the hydraulic characteristics of the vertical slit fishway with different sides are experimentally studied.The velocity and depth of the vertical slit of the fishway under different working conditions are studied and analyzed.The results show that under different water level conditions,the velocity in the fishway remains constant and full.Migratory conditions of podocars.
