Abstract
This paper presents field evidence in support of the energy-base procedure to predict the liquefaction potential of soil deposits. Two recorded earthquake events which occurred at the Wildlife Site: Elmore Ranch earthquake (11/23/1987) and Superstition Hills earthquake (11/24/1987), representing nonliquefaction and liquefaction case histories respectively, were utilized to verify the energybased procedure in field situations. The nonlinearity and the degradation of shear stiffness and strength of soil deposits subjected to earthquake loading under undrained conditions were incorporated in the reconstruction of the shear stress-stain response. The effects of multi-directional excitation on the liquefaction potential and the build-up of pore water pressure were also investigated. Finally, a unit energy-pore pressure model was confirmed by the comparison of the calculated and recorded pore ressure time histories.
