英文摘要	Based on the shear beam theory of homogeneous soil layer, the motion equation of the soil slope was established under the horizontal earthquake, and the horizontal displacement and acceleration response of the slope were solved. The defects of the assumptions of rigid slope and constant acceleration along the slope hight were improved by using the pseudo-dynamic method in the analysis and the horizontal acceleration solved in the calculation of seismic earth pressure. Then the formulas for calculating the active and passive earth pressure were derived. Considering the situations in practical engineering, the influences of the angle of filling soil behind retaining wall, the internal friction angle, and the interfacce friction angle between retaining wall and filling soil on the total earth pressure were analyzed and the improved method was compared with the traditional ones. The results show that the seismic earth pressure is like a sine or cosine wave in time domain. The seismic active and passive earth pressures increase with the increase of the angle of filling soil behind retaining wall. The total seismic active earth pressure decreases with the increase of internal friction angle and filling interface friction angle gradually, while the total passive earth pressure increases. The traditional methods are not safe due to that their results are usually inclined to the small side. © 2016, Editorial Office of Journal of Vibration and Shock. All right reserved.
