Abstract According to soil arching effect，stresses on the wall and sliding plane of the sliding backfill mass at arbitrary depth is obtained. And the pseudo-static method and total force equilibrium，a new formula of the seismic active failure angle behind non-vertical rigid retaining wall is obtained under translation mode. Then according to differential level layer method，by force and moment equilibrium，new formulae of the seismic active earth pressure against non-vertical rigid retaining wall and its coefficient are putted forward under translation mode. And those of the seismic active earth force，its coefficient and the application height are also derived. The distribution of seismic active earth pressure by proposed formula is non-linear along the height of wall. In addition，The influences of on the wall-back inclination，internal friction angle of backfill，wall-soil friction angle，seismic coefficient and load against the backfill surface on the seismic failure angle，seismic active earth pressure and its coefficient，seismic active earth force and height of its application are investigated.
