中文摘要:
      为了探明不同进口朝向的布置方式和进口位置对诱鱼效果的影响,本文通过建立鱼道进口概化模型,设计3种环境流速工况,在不同朝向和不同位置鱼道进口分别进行放鱼试验。结果表明:在同一鱼道进口位置时,垂直于河道水流方向上的鱼道进口,其诱鱼效果明显优于顺河道水流方向的鱼道进口;在鱼道位于河中央时,鱼道进口越靠近电站尾水,诱鱼效果越好;在所设计试验工况中,环境流速为0.3m/s时,鱼道进口诱鱼效果最好。研究结果将对水利工程中鱼道进口布置具有重要的参考意义并指导工程实践。
英文摘要:
      In order to find out the influence of different entrance orientations and positions on fish attractive effect, a generalized model of fishway entrance was established and three environmental velocity conditions were designed in this paper. Tests were carried out at fishway entrance of different orientations and positions. The results showed that the fishway entrance in the direction perpendicular to the river flow had better attractive effect than the one in the direction parallel to the river flow at the same fishway entrance; When the fishway is located in the middle of the river, the closer the fishway entrance is to the tail water of the power station, the better the fish luring effect will be; In all conditions, when the environmental velocity is 0.3m/s, there is the best attractive effect for the fishway entrance. The research results will have important reference significance for the layout of fishway entrance in hydraulic engineering and guide the engineering practice.
