摘要:
大坝和堤堰等水工建筑物的修建截断了河流，使河流中鱼类的栖息地及洄游路线受到极为严重的干扰。为了解决鱼类的洄游问题，修建鱼道是广泛采用的工程措施，其中，以竖缝式鱼道的数量居多。本文从竖缝式鱼道的长挡板细部构造入手，通过模型实验的手段，对比分析了三种方案对竖缝式鱼道鱼池流速的影响。通过研究，推荐竖缝式鱼道的长挡板结构型式为“直钩”型。
Abstract:
The construction of dam and burrock blocks the river basin, and affects the migratory route of fishes. Fishways are widely used as engineering measures to guarantee the migration of fish. The vertical slot fishway is the most common type. This paper presents the results of an experimental work with three different long baffle schemes on the vertical slot fishway. The values of velocity are indicated by the results. Above all three schemes, “straight hook” type is recommended as the type for long baffle structure of the vertical slot fishway.
