主　　题：Reinforced embankment Stability Seismic behavior Shaking table model test 

摘      要：The stability and seismic behavior of geosynthetic-reinforced embankments during the earthquake is not well *** this paper,the damage types of embankments were summarized,and the seismic stability of reinforced embankment were analyzed through an earthquake damage investigation in the Wenchuan earthquake ***,large-scale shaking table model tests were performed on the geosynthetic-reinforced *** results show that the damage level of the reinforced embankment was almost less than that of the unreinforced *** peak seismic earth pressure was nonlinear along the height of the embankment,the largest peak seismic earth pressure was roughly in the middle of the embankment *** peak ground accelerations(PGA)amplification factor first showed an increasing pattern and then a decreasing pattern with the increase of elevation,but there was a final increasing trend along the height of the reinforced *** results can help to establish the proper design of the reinforcement embankments under earthquake conditions.
