同侧导竖式鱼道水力特性试验研究

Hydraulic Characteristics of Vertical Cross-set Slots Fishway with Deflecting Block

以某水电站鱼道体型为研究基础,通过1∶10鱼道局部模型,对同侧竖缝式池室的水力特性进行了试验研究,得到了过鱼池室流态、流速分布以及适合目标鱼类上溯的路径等,并对隔板体型、竖缝宽度以及池室长度等进行了分析论证。试验结果表明,该隔板型式、池室尺寸以及池底坡度的同侧导竖式鱼道参数设计基本合理,比较适合需要保护的4大家鱼洄游上溯。通过活鱼试验,验证了鱼类上溯喜好的水力条件等。

The hydraulic characteristics in the pool of vertical cross-set slots fishway with deflecting block were re- searched through 1：10 partial fishway model test. The hydraulic factors such as flow regime, velocity distribution in the pool and the suitable upstream path for targeted fishes were observed, and the baffle shape, slot width and pool length were analyzed. The results verified the rationality of the baffle type, pool size, and parameters of the fish-way. Through live fish experiment, we get the physiological characteristics and hydraulic conditions favorable for the breeding migration of four major Chinese carps.
