小石峡水电站集运鱼系统设计研究

The design of fish collection and transportation system for Xiaoshixia Hydropower Station

小石峡水电站位于阿克苏河支流库玛拉克河中上游段,工程于2012年投产发电。为恢复河段连通性,促进坝上下游鱼类基因交流,2016年提出应补建集运鱼系统。在河段鱼类资源调查基础上明确了过鱼目标,结合鱼类游泳能力测试及模型试验,对小石峡水电站集运鱼系统工艺设计和系统设计进行了重点研究,推荐采取“固定式集鱼平台+公路转运+滑槽放流”的总体过鱼方案。研究成果可为新建中高坝工程、已建工程补建过鱼设施提供借鉴。

Xiaoshixia hydropower station is located in the upper and middle reaches of the Kumalake River,a tributary of the Aksu River,the station went into production in 2012. In order to restore river connectivity and promote fish gene exchange,it was proposed that fish collection and transportation system should be built in 2016. On the basis of the investigation of fish resources,the fish objects have been defined. Combined with fish swimming ability tests and hydraulic model tests,the paper focuses on the process design and system design of fish collection and transportation system of the station. The fish passing scheme is determined as the“Fixed fish-collectingplatform + Road transfer + Spout releasing”.The research results can be used for reference in the newly-built middle-high dam projects and the completed projects.
