通过实例计算,定量地分析了结构内部损伤度、损伤位置和损伤区域大小对接收波幅值和波到达时间的影响。
By the examples computation, the effects of the damage degree, damage location and zone on the amplitude and the arrival time of the received wave were quantitatively analyzed.
通常,波长较短传播较慢—但是破坏性要大的多—的S波会随之而来。 通过这两种波到达时间的差值可以估算震中的距离。
type of waves can be used to estimate distance to the epicenter.
因此,实际观测得到的反射波到达时间,并不是标准的双曲线,而是一条畸变了的双曲线,从而影响速度分析和迭加效果的质量。
Therefore, the actual observation obtains the reflection time, is not the standard hyperbolic curve, but was a distortion hyperbolic curve, thus influence speed analysis and iteration effect quality.
