Abstract

In this research, we discussed about the wave induced seabed liquefaction at nearshore based on the viewpoint of marine geotechnical engineering. The behaviors of seabed sand under wave loading were evaluated by experiments carried out in the Chien’s cyclic triaxial testing system (type II). Different loading periods, effective confining pressure and relative densities affected the liquefaction resistance of seabed sand that we sampled at northeastern coast in Taiwan. Furthermore, this study proposed the 3-D evaluation method of seabed liquefaction at Yi-Lan nearshore in case that combined the liquefaction resistance of seabed sand and Nearshore Spectral Windwave (NSW) model. The new 3-D method could evaluate the distribution and thickness of wave-induced seabed liquefaction at nearshore area.
