STUDY ON WAVE-INDUCED PROGRESSIVE LIQUEFACTION OF A PORO-ELSTOPLASTIC SEABED: VISCOUS EFFECTS

摘要：

In this study, the prediction model proposed by Sassa et al. (2001) for the wave-induced progressive liquefaction in marine sediment, based on two-layered inviscid fluid system, is re-examined. An alternative approach with a similar framework of Sassa et al. (2001) is developed to correct the inappropriate mechanism of wave components. Then, a two layered wave model with viscous effects is established and applied to describe the progressive nature of wave-induced liquefaction. A comprehensive comparison shows that Sassa’s model overestimates the liquefaction depth. A parametric study is conducted to show significant influence of numerous wave and soil characteristics on the liquefaction depth.
