Abstract：The seismic dynamic response of slope is a very complex problem，and the factors that affect the dynamic response of slope are various. In this paper，the dynamic response characteristics of anchor sheet pile wall under earthquake are studied by shaking table test. By observing the macroscopic failure phenomenon of the anchor sheet pile wall model after the earthquake，it is found that the trailing edge of the sliding body is easy to be damaged by tensile failure under the action of strong earthquake，and the damage accumulates continuously. When the peak acceleration reaches 0.9 g，the cracks at the trailing edge of the landslide are completely connected，which is 4 times that of 0.4 g. Through the analysis of the monitoring data of the monitoring points，it is found that the model is sensitive to the difference of seismic wave spectrum. The earth pressure on the back of the wall shows an irregular “inverted trapezoid”，peaking at about 10 cm below the top of the pile. Under EL-Centro earthquake excitation，the amplification effect of each measuring point changes linearly with the increase of PGA，and is scattered between 0.8 and 1.6，while under Wolong earthquake excitation，the amplification effect of each measuring point changes nonlinearly with the increase of PGA，mainly concentrated around 1.4. It can be seen that the acceleration amplification factor of the measuring point away from the anti-slide pile is much smaller than that of the measuring point near the anti-slide pile，indicating that the soil structure near the anti-slide pile is more complete.
