Liquefaction Prediction in the Marine Environment

Abstract

Cyclic shear stress reversals are induced in seabed sediments either by pressure fluctuations caused by the passage of a wave train or by transmission through an offshore structure subjected to wave forces. In both cases a consequent build-up of excess pore-water pressure has been observed with the use of piezometer probes. The resulting loss of effective stress can potentially lead to a state of liquefaction in marine sands and silts.
