Many hydraulic experiments have been carried out on the physical elucidation of lift force and shock wave pressure. In recent years, computational techniques have been developed and wave pres-sure is being studied using numerical calculations. However, there are few case studies by numerical calculation for phenomena such as lift force because it makes huge time to calculate complex wave pressures. In this study, we conducted hydraulic experiments on the pier, and compared with the cal-culations using the gas-liquid phase fluid simulation. Furthermore, we investigated the accuracy of reproducibility calculations for incompressible fluid and possibility of applying calculation to prac-tice. Although, it remains problem to reproduce the experimental values sufficiently by numerical calculation, it was possible to catch the momentum of the water mass. It is necessary to study the compression effect and the reduction of calculation cost.
