POST-LIQUEFACTION PROCESS BASED ON THE SEDIMENTATION OF SAND PARTICLES

A number of researches have been performed to identify the conditions under which the liquefaction occurs. Moreover, the characteristics of liquefied soils under seismic excitations have been investigated by recent studies. A little have been studied on the post-liquefaction process although its characteristics would be important for understanding the mechanism of the liquefaction-induced ground movement and the related damege to the structures. In this papar, therefore, a simplified post-liquefaction theory is derived based on the sedimentation of sand particles, and after its validity is confirmed by the simulation of the recent experimental works.
