摘要
鱼道进口的布置除受其自身布置原则的限制之外,还受到枢纽布置及河势、地形、地质、下游水位等其他边界条件的限制。为同时满足以上双重要求,对某工程鱼道进口的布置进行深入研究,提出一种能满足边界条件及绝大部分布置原则的初步布置方案。对该初步布置方案中不能满足布置原则的采取相应的工程措施加以优化。水工模型验证表明,优化后的鱼道进口布置方案对河道中的洄游鱼类具有较大的吸引能力,在流量、流态、水深及流速等方面。
Excepting the layout principles,the layout scheme of fishway entrance is constrained by the boundary conditions of hydro-project layout,river pattern,topography,geology and downstream water level etc.Aimed to layout principles and boundary conditions,layout schemes of a fishway entrance is studied deeply,an initial layout scheme meeting the boundary conditions and the most layout principles is proposed.Then,the initial layout scheme is optimized by corresponding engineering measurements to meet the other layout principles which the initial layout scheme can＇t meet.It is showed by the hydro model experiment that the optimism layout scheme of fishway entrance has a better attractivity to the fish migration in the river and can better meet design requirements of flow discharges,flow patterns,depth of water and velocities.
