The expressions for anti-overturning and anti-slipping stability coefficients and equations are derived by using the formula for active pressure of wall under different failure mode. The variation characteristics of earth pressure acting on the wall, angle of rupture and stability of are investigated under four cases. The reliability of two checking methods presented by the specification are compared and analyzed. Finally, the influence of the internal friction angle of the backfill on the stability is analyzed, for reference.
