Under each water level, the foundation radiation damping brings overall reduction of the dam body's earthquake responses, while having no noticeable effect on the response patterns.
对所有水位，地基辐射阻尼都带来坝体地震响应的全面降低，但不影响反应的总体规律。
Artificial damping boundary is adopted in seismic model test of arch dam on shaking table to simulate the radiation damping effect due to energy dissipation in infinitive foundation.
在振动台上进行拱坝动力模型试验时，设置人工阻尼边界，以模拟地震时地震动能量向无限远域地基逸散的地基幅射阻尼效应。
