Based on the characteristic of the emergence of large ground displacement and some reasonable hypothesis, the authors pose a method for calculation large ground displacement induced by seismic liquefaction and make an initial study on its possible influencing factors. In calculation lateral ground displacement emerging during earthquake, this method is able to reflect fairly truthfully its physical mechanism and to reveal the regular pattern of its emergence, as shown by the reckoning which coincides with macroscopic phenomenon of seismic damage.
