多布水电站鱼道工程设计符合性检验及改进措施研究

Study on Design Compliance Inspection and Improvement Measures of Fishway at Duobu Hydropower Station

鱼道作为主要过鱼设施类型被应用于缓解大坝对鱼类洄游的阻隔影响,近年来国内建成的鱼道工程大多采用竖缝式鱼道。由于施工工艺和方法等因素,竖缝式鱼道施工常出现设计符合性偏差问题,影响鱼道工程预期过鱼效果,进行设计符合性检验,分析工程施工与设计不相符导致的功能损失。通过以多布水电站鱼道工程为例,开展鱼道工程设计符合性检验,针对鱼道工程存在问题提出改进措施并分析效果,提升了多布水电站鱼道运行效果和管理能力,可为国内同类鱼道建设提供参考。

As the main type of fish passage facilities,fishways are used to alleviate the barrier effect of dams on fish migration.Due to factors such as construction technology and methods,there is deviation in the design compliance of the vertical slot fishway,which affects the expected passage effect of fishway.However,carrying out the design compliance inspection can verify the functional loss caused by nonconformity between project construction and design scheme.This study takes the fishway at Duobu Hydropower Station as an example to carry out design compliance inspection.Aiming at the existing problems of the project,the improvement measures are proposed and the effects after improvement are analyzed,which improves the operation effect and management ability of the fishway at Duobu Hydropower Station.The study can provide reference for the construction of similar fishways in China.
