Three shaking table tests were carried out to investigate the influence of loading frequency on seismic performance of MSE walls constructed with full-height panel facing. Results of this study provide quantitative results on how base excitation frequency in combination with base acceleration amplitude could influence the dynamic response of these MSE walls relative to their deformations, earth pressures, acceleration amplifications and connection loads. Results indicate that model walls responded primarily in tilting mode. However, base sliding could also occur as an additional deformation mode at larger base excitation amplitudes, and at frequencies that are closer to the fundamental frequency of the wall, resulting in significant connection loads and other response characteristics. Findings of the study are compared with results from other studies and recommendations in design guidelines, as applicable.

进行了三个振动台测试，以研究加载频率对全高面板式MSE墙抗震性能的影响。这项研究的结果提供了定量的结果，说明基本激励频率与基本加速度幅值如何影响这些MSE壁相对于其变形，土压力，加速度放大和连接载荷的动力响应。结果表明模型墙主要在倾斜模式下响应。但是，在较大的基本激励振幅和更接近壁的基本频率的频率下，基本滑动也可能作为附加的变形模式发生，从而导致明显的连接负载和其他响应特性。
