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...

INTRODUCTION Nowadays, many offshore structures have been commonly constructed over the last few decades due to the growing engineering...

... stability is a vital problem for coastal engineers. In general, the propagating ocean wave will generate the dynamic pressure in the sea floor, which may trigger soil liquefaction of the seabed as reported in the laboratory test (Sassa and Sekiguchi, 1999). Meanwhile, the effect of earthquake is also...

... and residual mechanisms of the pore pressure inside the soil. A parametric study is conducted to examine the characteristics of the poro-elastoplastic model here. It shows that the development of the two-dimensional liquefaction zone can be illustrated by the present model. Besides, results show that opposite...

... Abstract In this study, a one-dimensional experimental study for the influence of clayey soils on wave-induced liquefaction was reported. The one- dimensional facility was set-up with a vertical cylinder and a 1.8 m thick deposit and 0.2 m thick water above the deposit. Unlike the previous...

... results, we concluded that, the liquefaction zone develops first in front of and at the toe of the rubble- mound breakwater and then extends laterally and vertically to neighbouring zones. Under certain conditions, this two liquefied zone will be eventually linked together. liquefaction artificial...

... 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...
