摘      要：The wave-induced liquefaction of seabed is responsible for causing damage to marine *** composition and consolidation degree are the key factors affecting the pore water pressure response and liquefaction behavior of the seabed under wave *** present study conducted wave flume experiments on silt and silty fine sand beds with varying particle ***,a comprehensive analysis of the differences and underlying reasons for liquefaction behavior in two different types of soil was conducted from both macroscopic and microscopic *** experimental results indicate that the silt bed necessitates a lower wave load intensity to attain the liquefaction state in comparison to the silty fine sand ***,the duration and development depth of liquefaction are greater in the silt *** dissimilarity in liquefaction behavior between the two types of soil can be attributed to the variation in their permeability and plastic deformation *** permeability coefficient and compression modulus of silt are lower than those of silty fine ***,silt is more prone to the accumulation of pore pressure and subsequent liquefaction under external *** research has demonstrated that silt beds with varying consolidation degrees exhibit distinct initial failure ***,a dense bed undergoes shear failure,whereas a loose bed experiences initial liquefaction *** study utilized discrete element simulation to examine the microscopic mechanisms that underlie this phenomenon.
