Aiming at the problem of sluice flow, based on the smooth particle hydrodynamics method (SPH), the boundary treatment method was improved, and the main parameters of repulsion force were re-calibrated, which can avoid non-physical oscillation with n1=4 and n2=2. At the same time, the comparison and selection of water replenishment modes were carried out, and it was clear that the bottom hole water replenishment mode with 3 m elevation difference in the optimal water replenishment mode can reduce the net outflow of particles from the upstream water body. On this basis, the numerical model of the flow through the gate impacting the stilling pool downstream was established, and the process of the flow from the sluice to the stilling pool was simulated. The results show that at the initial time, the maximum pressure at the bottom of the upstream water is 127.4 kPa; At the 7th second, the average velocity at the right end of the stilling pool is 7.07 m/s, at the 19th second, the average velocity at the right end of the stilling pool decreases to 1.4 m/s. Thus, the SPH method can accurately simulate the changes of flow velocity, pressure and flow pattern in the discharge process.
