摘　　要：本文对同侧竖缝式鱼道的水力特性进行了系统的试验研究。试验在沈阳农业大学水利学院水工大厅进行,鱼道模型比尺为1∶5,选择了3组底坡(i=1/50、1/72.7、1/90),3组流量(Q=9.34L/s、11.21L/s、14.14L/s),实测了0.26h、0.52h平面的流速分布(h为相应流量水深),流速由声学多普勒流速仪测量。分析了同侧竖缝式鱼道的主流曲线分布特征、主流速度沿程变化规律、竖缝断面处流速变化规律。This paper presents a systematic experimental study of hydraulic characteristics in one-side vertical slot fishway that was conducted at Shenyang Agricultural University.This model had a scale of 1∶5,and three slopes(i=1/50,1/72.7,1/90) and three discharges(Q=9.34L/s,11.21L/s,14.14L/s) were tested.For each discharge,velocity profiles on two horizontal planes of 0.26h and 0.52h(where h denotes the pool depth) were systematically measured with an ADV.The behavior of main flow path,the streamwise variations of maximum velocity and the pattern of velocity variation along the vertical slot are analyzed.
