以日本防灾科学技术研究所(NIED)K-NET,KiK-net强震数据库的宽频数字记录为基础,基于记录的地震数据分为钻孔基岩和地表土层,分别进行了V/H加速度峰值比以及反应谱比的统计分析。通过研究得出以下结论:竖向地震动分量和水平分量的峰值比和反应谱比不仅与场地条件有关,还与震中距、震级等因素有关;基岩和土层V/H加速度峰值比及反应谱比区别很大,由于竖向地震分量与水平分量的频率特性不同,地表土层效应对水平地震分量与竖向分量产生了不同的影响。
Based on the broadband digital records of the K-NET and KiK-net Strong Earthquake Databases of the Japan Institute of Disaster Prevention Science and Technology (NIED), based on the recorded seismic data, the bedrock and surface soil layers are divided into two types: V / H Acceleration peak ratio and response spectrum ratio of statistical analysis. The conclusions drawn from the research are as follows: The peak ratio and response spectrum ratio of vertical ground motion component and horizontal component are not only related to the site conditions, but also to the epicentral distance, magnitude and other factors; peak V / H acceleration ratio of bedrock and soil layer and The response spectrum ratio is very different. Because of the different frequency characteristics of vertical seismic component and horizontal component, surface soil effect has different effects on horizontal seismic component and vertical component.
