摘要
通过引入筋-土、面板-土、面板-面板接触单元,建立由土体单元、接触单元、面板单元和加筋材单元组合的加筋土挡墙有限元模型,用ANSYS对一足尺加筋土挡墙进行了有限元数值模拟.主要研究了地震荷载的频率成分和最大水平加速度对加筋土挡墙地震下性能的影响,得出了一些关于加筋土挡墙动力响应的定性结论.
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.
