The water flow disorder, shock, spray splashing out of the side wall and incomplete water jump are often caused by insufficient discharge energy dissipation in the pool. In order to solve this problem, the influence law of the layout of T-shaped pier and its parameter variation on the hydraulic characteristics in the ballast tank was studied by using the model test method and numerical simulation. The results show that the energy dissipation rate increases with the increase of the length of T-shaped pier legs; The water depth increases with the installation of the impingement baffle, and the efficiency increases, and the energy dissipation rate decreases with the increase of the impingement baffle; The flow state of the water in the stilling pool is stable after the double-row T-shaped piers are arranged, and the energy dissipation increases first and then decreases with the increase of the distance between the front and back. According to the simulation results, a reasonable scheme is recommended and verified by model test. The results show that the energy dissipation rate of the recommended scheme reaches 76.06%, which increases by 12.51%. The flow state is stable and meets the engineering requirements.
