摘要

摘要: 近年来，地脉动水平/竖向谱比法广泛应用于获取场地卓越频率工作中，但在指示地震动放大系数方面是偏小的。利用KiK-net台网403个台站共21万余组数据，通过对比分析地脉动水平/竖向谱比MHVR和地震动水平/竖向谱比EHVR，发现二者的谱形和峰值频率基本一致，但幅值存在差异。根据MHVR谱形将场地分为6类，建立将MHVR修正为EHVR的经验方法。当MHVR有可解释的峰值时，实测EHVR和修正后MHVR预测值一致性提高。地震动峰值加速度在40 cm/s²以下时，EHVR受场地非线性的影响较小，利用MHVR及其修正方法可有效估计EHVR。

Abstract: In recent years, the horizontal/vertical spectrum ratio method of microtremor has been widely used to obtain the site dominant frequency, but it is usually too small to indicate the amplification coefficient of ground motion. Based on more than 210,000 sets of data from 403 stations of KiK-net, the horizontal/vertical spectrum ratio of microtremor (MHVR) and horizontal/vertical spectrum ratio of earthquake ground motion (EHVR) are compared and analyzed. It is found that the spectrum shape and peak frequency of the two are consistent, but the amplitude is different. According to the MHVR spectrum, the site was divided into six categories, and an empirical method was established to modify MHVR into EHVR. When MHVR has an interpretable peak value, the consistency between the measured EHVR and the revised MHVR predicted value is significantly improved. When the peak acceleration of ground motion is less than 40 cm/s², EHVR is less affected by site nonlinearity. Therefore, MHVR and its correction method could be used to estimate EHVR effectively.
