An effective stress analysis procedure is proposed for simulating dynamic response of a soil deposit involving soil liquefaction and cyclic mobility. The analysis is coupled with an effective stress model which can define stress-strain relationship of liquefiable sand with a limited number of parameters. The effectiveness of the proposed analysis is studied using the accelerations and pore pressures which were recorded in a soil deposit during six earthquakes. The analytical results including time histories of acceleration and pore pressure and Fourier acceleration spectra are in good agreement with the observed values, indicating that the proposed analysis is effective.
