Abstract
Generally it is thought that occurrence of excess pore water pressure in liquefied ground leads to the 11 loss of shear strength and shear modulus and dissipation of excess pore water pressure recovers the state of the liquefied ground compared with the ground before liquefaction occurred by earthquake. Therefore, it is rare to report results of investigation to compare the states of the ground before and after liquefaction systematically. In this study, laboratory experiment with small rigid container was carried out to assess the behavior of the model ground after liquefaction by measurement of shear velocity, differential leveling and sounding tests during 5 month. This paper describes the recovery of shear modulus and penetration resistance occurred with increase in volumetric strain.
