• The writers have previously proposed equations to predict pore-pressure rise under uniform and non-uniform dynamic shear stresses for a saturated Ottawa sand based on the results obtained from undrained cyclic shear experiments in the Torsional Simple Shear Device. In this paper, they extend those previous studies to earthquake-type loadings and to saturated Ottawa sand at different densities and propose equations that predict the pore-pressure rise during earthquake-type loadings.The predicted and the measured pore pressures under earthquake-type shear stresses are compared, and a good correlation between the two is obtained.A diagram and a table are presented from which the four material parameters, C_1,C_2,C_3 and α, used in the above pore-pressure prediction equations can be readily obtained for any given void ratio or soil density.
