Numerical models of the gravity retaining wall and the reinforced earth retaining wall based on Flac3D were established in order to compare with the seismic performance based on the wall horizontal displacement time-distance curve, and analyze the influence of wall height and earthquake intensity on them. The results show that it is obviously different on dynamic performance between gravity retaining wall and reinforced earth retaining wall, the latter’s seismic performance is better than the former.
