Based on the action mechanism of the frame prestressed anchor slope supporting structure, combined with the pseudo-dynamic method, the acceleration distribution on the half plane is solved by the seismic wave theory, assuming that the seismic waves are simple harmonics. In the case of prestress, the potential sliding surface of slope is determined by derivation of the ratio of anti-sliding force and sliding force under dynamic action. Combined with horizontal layer analysis method, the active earth pressure of prestressed anchor slope supporting structure under simple harmonic earthquake is solved. Finally, the soil pressure variation of the frame bolting structure under the harmonic seismic action is compared with the engineering case. The results show that the higher prestress can restrain the variation range of seismic earth pressure.
