双江口水电站过鱼方案比选分析

Comparative analysis on fish passage scheme for Shuangjiangkou Hydropower Station

由于双江口水电站的坝高、水库面积大以及地形复杂等因素,大大制约了过鱼设施的布置。本文结合双江口水电站枢纽工程布置、水库情况和鱼类资源等特点拟定了4种过鱼方案进行比选,选定了适合该工程实际的过鱼措施,是国内同类型项目的第一次尝试,研究所得成果对同类工程有一定的借鉴作用。

Due to the high dam height, large reservoir area and complicated landform, the arrangement of fish passage facility is largely restricted for Shuangjiangkou Hydropower Station. Combined with the characteristics of the hydropower station, such as the project layout, the condition of the reservoir, the fish resources, etc. , 4 fish passage schemes are comparatively selected, and then a fish passage measure suitable for the actual condition of the project is determined, which is the first trial within the similar projects in China and the result from the study can provide certain references for the similar projects as well.
