根据相似关系得到了原结构的在给定的常遇和罕遇人工地震波激励下的动力响应。
According to the similarity relationship, dynamic response of the real bridge structure is got under the action of given general and unusual simulation seismic excitations.
人工地震波、电磁波和声波的频率越高，分辨率越高，但衰减快，可探测深度也降低。
The higher the frequency of the artificial earthquake wave, electromagnetic wave and sonic wave, the higher the resolution, but the attenuation is very fast and the exploration depth is very shallow.
地震模拟振动台试验不仅负载量大，而且能模拟天然地震波和人工地震波对试件加载。
Shaking table experiment not only has great load factor, but also can simulate crude seismic wave and artificial wave to load tested object.
