In this research, in order to confirm the acceleration behavior of the secondary consolidation, a comparatively long consolidation test (about 1 year) was carried out. And in order to investigate the dissipation delay of the excess pore water pressure in consolidation test, a reproduction analysis was carried out in consideration of the density dependency of the coefficient of permeability.
