孤山航电枢纽工程鱼道布置设计

Layout and research on fishway of Gushan Navigation and Hydropower Project

为尽可能地减小孤山航电枢纽工程建成后阻隔鱼类上溯通道产生的不良影响,对鱼道、鱼闸、升鱼机和集运渔船等过鱼设施型式进行经济技术比选,并结合孤山航电枢纽布置、运行水位、过鱼对象的洄游习性及克流能力等方面进行鱼道设计。通过物理模型试验对布置结果进行验证,结果表明:所设计鱼道在各级运行水位及工况组合下,鱼道进鱼口、出鱼口处水流条件均满足过鱼要求。

In order to reduce the adverse effects of fish on the upstream channel after the completion of the Gushan Navigation and Hydropower Project as much as possible,the engineering fishway layout and design were carried out.The types of fish passage facilities such as fishway,fish lock,fish lift and collection and transportation fishing vessel were compared and selected technically and economically,and the design was carried out in combination with the layout of Gushan Navigation and Hydropower Station,topographic address,operating water level,migratory habits of fish passing objects and flow capacity.The results were verified by physical model experiments,which showed that the flow conditions at the inlet and outlet of the fishway can meet the requirements of fish passage under the combination of operating water levels and working conditions at all levels.
