Experimental Study and Calculation of Wave Force Acting on the Offshore Structures in Shallow Sea Water

The wave force acting on a vertical pile in shallow sea water is calculated by using second order conidal wave theory, second order hyperbolic wave theory and second order solitary wave theory. An experimental study on wave parameters, wave forces and wave pressures are carried out in a wave channel. Based on the experimental data,the traditional computing method of wave force is corrected, and a correction formula is suggested. The theoretical wave pressure can be calculated by means of conidal and hyperbolic wave theories, and the wave forces can be calculated by integral of the corrected pressures around the pile with the instantaneous wave surface as the upper limit. Compared with the experimental data, this method gives the reasonable results.
