Validity Verification and Correction Method of Horizontal and Vertical Spectrum Ratio Method of Microtremor in Site Effect Study

  • 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。
