【摘要】 为评价使用各种方法获得地震动加速度时程与区域内地震动加速度时程观测资料的一致性,提出一种能够综合时频特性的地震动时程一致性评价指标及其相对性判据,该方法可以量化分析待评价地震动时程对区域构造信息的反映能力。通过评价唐山地区陡河地震台和四座楼地震台模拟结果与实际观测结果的一致性,给出了实用化的算例。更多还原

【Abstract】 To evaluate the consistence of the seismic ground acceleration time history between by use of different method and regional observation,we put forward a kind of assessment index of the consistence of the seismic ground time history which could synthesize the time-frequency characteristics and its relative consistency criterion. This method could quantitatively analyze the reflection ability of evaluated seismic ground time history on the regional tectonic information. We compared the simulation result with the realistic observation result of Tangshan M4. 7earthquake in 2012 recorded by Douhe Station and Sizuoluo Station in Tangshan area,and gave a practical example.更多还原
