Abstract	In order to investigate the variation of the seismic response spectrum of slope reinforced with piles under the liquefaction of saturated subgrade, some acceleration sensors are used to record the seismic acceleration response of slope reinforced with stabilizing piles under the waterless condition and the saturated subgrade in the dynamic centrifuge modeling test, respectively. Then the different characteristics of the acceleration spectrum of seismic response are analyzed through the comparisons. The results prove that seismic response amplifies from bottom to top of the slope under the waterless condition, showing that seismic response is larger at the top of slope than that at the bottom of slope; however, seismic response of slope is restrained to a certain extent due to the liquefaction of saturated subgrade, so that seismic acceleration response of the soil mass of slope shall decrease at first with the increasing of elevation and then increase slightly. Moreover, due to the liquefaction, the low and intermediate frequency components of seismic response are reinforced to some extent, which reflects the reduction of global rigidity of the reinforced slope caused by liquefaction.
