| Abstract | ||
| During seismic events or wave loadings, the stability of dock and marine structures founded on liquefiable soils becomes a major concern. In this paper, a liquefaction assessment for a dock structure founded on liquefiable soils, subjected to different earthquake excitations, is presented. The liquefaction assessment is based on intensive cone penetration testing over water. The results of the study indicate that a significant increase in liquefaction potential occurs with the increase in water depth. The global stability of the dock structure is assessed using a pseudo-static approach. The study indicates that a soil treatment or densification zone equivalent to about twice the width of the slope under the dock is required to avoid the structural collapse during a major seismic event. | ||
