Abstract: This paper deals with the investigation of nonlinear effect of waves on wave pressure and waveforce on a large cylindrical pile. Based on the numerical computation of the second order ap-proximate solution of nonlinear diffraction theory by the authors, it is clarified that nonlinear effectof waves on the maximum total wave force is of less importance except for the case of small valueof the ratio of water depth to wave length. In the next, from the comparison between the theoreticalcurves and the experimental results for wave pressure and total wave force, the validity of the theoryis confirmed. Especially, it is found that the nonlinear effect of waves on the pressure appearsremarkably in front of a pile and that the time variation becomes more asymmetrical toward theside of a pile.
