高坝过鱼设施集诱鱼口位置及设计参数体系研究

Research on Fish Inlet Location and Design Parameter System of Fish-passing Facility in High Dam

黄河羊曲水电站为黄河上游首个建设高坝过鱼设施的大型水电站,对于恢复黄河上游河段土著鱼类生境连通具有重要意义。高坝过鱼设施设计要充分考虑鱼类生物学特征和河段流场基本条件,确定合适的诱鱼口位置和运行参数。通过开展鱼类资源调查、鱼类游泳能力测试、坝下流场模拟分析、水力学模型试验等多项基础工作,确定过鱼设施诱鱼口位置及设计参数体系。研究方法和成果对于黄河上游其他规划水电工程高坝过鱼设施设计工作具有很强的借鉴意义。

Yangqu Hydropower Project is the first large hydropower project in the upper reaches of Yellow River to construct high-dam fish-passing facility,which is of great significance for restoring the habitat connectivity of indigenous fishes in the upper reaches of Yellow River.The design of high-dam fish-passing facilities should fully consider the biological characteristics of fishes and the basic conditions of river flow to determine the appropriate location and operating parameters of fish-passing facilities.By carrying out fish resource survey,fish swimming ability test,numerical simulation and model test of the flow field under the dam and other basic works,the fish inlet location and design parameter system of the fish-passing facility in Yangqu Hydropower Project are determined.The methods and results can be used as references for the design of fish-passing facilities in other planning hydropower projects in the upper reaches of Yellow River.
