Pseudo-dynamic analysis for seismic active earth pressure behind rigid retaining wall

WANG Zhi-kai,XIA Tang-dai,CHEN Wei-yun(Key Laboratory of Soft Soils and Geoenvironmental Engineering,Ministry of Education,Institute of Geotechnical Engineering,Zhejiang University,Hangzhou 310058,China)  
The effect of amplification of seismic accelerations was considered and a level-layer analysis method was suggested in order to obtain the theoretical formula for the distribution of active earth pressure under seismic loads based on the basic hypothesis of pseudo-dynamic method.The inclination of the most dangerous slip surface and the location of resultant force were compared with those of the traditional method.The effects of horizontal seismic acceleration coefficient and amplification factor on the distribution of seismic active earth pressure were analyzed.Results show that the values of the inclination of the most dangerous slip surface and the location of resultant force are larger than those obtained by the traditional methods.The location of resultant force is always changing during the earthquake.The horizontal seismic acceleration coefficient and the amplification factor significantly impact on the distribution of seismic active earth pressure,so it is dangerous to ignore the effect of amplification of seismic accelerations.
