In this research, we try to find a more practical formula for calculating the impact force of boulders. We infer an academic formula from the elastic collision theory. Then, in the experiments, we simulate the impact by debris flow with mixed diameters in order to correct the result formula. We hope we can provide a reference for future slit dam design and debris flow prevention.
