Seismic Behavior of Tied-Back Walls for Earthquake Hazard Mitigation

锚定挡土墙被广泛使用，但经常失败 在地震期间，造成严重的基础设施功能障碍， 长期经济影响。 然而，对极限的研究 作为抗震设计基础的回拉墙的（破坏）行为 这一点尚未得到证实，这也是本研究的目的。 具体而言，目的是在振动台上进行实验验证 滑块模型是否适用于预测极限行为 在地震荷载作用下的回拉式挡土墙。 主要研究人员拥有专业知识和机构 设施，以完成拟议的研究，这是 预计将大大推进挡土墙的抗震设计。

Anchored earth-retaining walls are in widespread use, and often fail during earthquakes, resulting in serious infrastructure disfunction and major long-term economic impact. However, studies of the limit (failure) behavior of tied-back walls on which to base a seismic design have not been made and this is the objective of this study. Specifically, the aim is to verify experimentally on a shaking table whether a sliding-block model is valid for predicting the limit behavior of tied-back retaining walls under earthquake loading. The principal investigators have the expertise and institutional facilities available to complete the research proposed, which is expected to advance significantly the seismic design of retaining walls.
