... of Jiangsu Province was simulated. By comparing the seabed response results of four tests with cover stones under the same wave conditions, it shows that the thickness and porosity of the cover stones are two important parameters of anti-liquefaction capacity. INTRODUCTION The stability of composite...

... Abstract The wave-induced pore pressure is a key factor in the prediction of the wave-induced liquefaction potential, which has been reported in the literature in conjunction with marine engineering (Sumer and Fredsøe, 2002). Most previous investigations for the wave-induced soil response have...
