Abstract

Abstract: In certain shallow water condition, shallow water wave may emerge in solitary wave form, exerting wave loads on offshore structures. Based on solitary wave diffraction theory and Biot seepage consolidation theory, the problem of solitary wave-induced seepage pressure inside porous elastic seabed is analyzed, the mathematical solution to seepage pressure is deduced, and seepage loads on the bottom of vertical cylinder resting on porous seabed are evaluated. The results show that variations of ocean condition and structure geometry condition may have some influence on solitary wave-induced seepage uplift force and moment, especially on seepage moment. In certain condition, solitary wave-induced seepage loads may have the same order of magnitude as the direct horizontal wave load

Key words: solitary wave, diffraction, radiation, wave force, seepage, wave-induced seepage uplift force and moment
