摘　　要：为了保证湘河生物多样性,降低水利枢纽工程建设对湘河生物多样性的影响,在工程设计过程中建设过鱼建筑物。根据当地鱼类特性,通过比选,采用鱼道作为过鱼建筑物,通过MIKE21FM模拟,采用两个进鱼口,各工况下鱼道的过水流量、水深均可满足过鱼要求;并对鱼道形式、出口、入口选择进行分析。可为类似工程过鱼建筑物设计提供参考。In order to ensure the biodiversity of the Xianghe River and reduce the impact of the construction of the water conservancy project on the biodiversity of the Xianghe River,a fish crossing structure was built in the process of the project design.According to the characteristics of the local fish,the fishway was selected as the fish crossing structure through comparison,and the MIKE21FM simulation showed that the flow rate and water depth of the fishway under different working conditions could meet the fish passing requirements.The form of fishway,the choice of exit and entrance are analyzed.It can provide a reference for the design of similar projects.
