| Abstract: | Through considering reinforcement-soil and faceplate-soil and faceplate-faceplate contact elements, the finite element model of reinforced retaining walls including soil elements, contact elements, faceplate elements and reinforcement elements was established. The numerical simulation study of reinforced retaining wall by ANSYS was conducted to investigate the influence of frequency content and the peak amplitude of the seismic load to the behavior of these structures under seismic load conditions, and some qualitative conclusions about their dynamic behavior were gained. |
