TOTAL WAVE FORCE ON A VERTICAL CIRCULAR CYLINDRICAL PILE

[摘要] This paper deals with the estimation of total wave force on a vertical circular cylindrical pile. Firstly, finite amplitude wave theories such as those of Stokes waves and cnoidal waves are recalculated by the Stokes second definition of wave celerity and the applicability of the theories for wave crest height above the still water level, wave celerity and horizontal water particle velocity is briefly discussed. Secondly, the drag and inertia coefficients are estimated respectively from the results of experiments for total wave force by the authors and by other researchers, based on the Morison wave force equation applying the theories and characteristics of the coefficients are considered in relation to the wave characteristics and pile dimension. Lastly, the applicability of the wave force equation proposed is investigated in comparison with experimental and theoretical results for time variation of total wave force and maximum total wave force.
