In order to solve the cavitation damage problem of the spillway with high head, three schemes were proposed. The aeration tank was added at pile number 0+130.73, 0+161.78 and 0+186.39, respectively, and the corresponding Fr was 6.65, 7.91 and 8.53. By means of RNG κ-ε turbulence model and physical model test, the aeration concentration and cavitation number indexes of the section prone to cavitation erosion were analyzed. The results show that the effect of adding aerator at pile 0+186.39 is better than the other two schemes, and the bottom aeration concentration is above 15% and the flow cavitation number is greater than 0.3 in the section prone to cavitation erosion, the cavitation failure problem in the drainage channel section can be effectively solved.
