摘　　要：针对竖缝式鱼道水力特性较复杂的特点,采用雷诺应力方程模型对同侧竖缝式鱼道池内的水流进行了二维数值模拟,并将数值模拟结果与物理模型试验结果进行了对比,验证了数值模型的正确性。进而建立了水池长宽比分别为5∶8、10∶8、12∶8三种鱼道模型,分别对底坡为1%、3%、5%三种条件下的鱼道水力特性进行了数值计算,得到了水流型态和竖缝最大流速、流速场、紊动能、雷诺应力等水流物理参数的分布规律。Aiming at the complicated hydraulic characteristics ot vertical slot tishway, two-dimensional numerical simulation of the water flow of vertical slot fishway on one side has been implemented by using Reynolds stress model （RSM）. Comparing the results of numerical simulation with physical model test, it verifies the correctness of the numerical simulation. Three fishway models are established under the tank length-width ratio of 5 ： 8, 10 ： 8, 12 ： 8, respectively. At the conditions of the bottom slope 1 %, 3 % and 5 %, hydraulic characteristics of fishway are simulated. Final ly, it obtains the distribution regularity of flow physical parameters about the flow patterns, vertical slot maximum velocity, velocity field, turbulent kinetic energy and Reynolds stress.
