| 摘 要： | 采用H/V谱比法,利用安徽强震台网记录的波形数据,计算了3个强震台的场地响应。结果表明,当台站场地为基岩或覆盖层较薄时,由地脉动和S波数据分别计算出的谱比曲线一致性很好。当覆盖层大于30.5 m的时候,两者的放大因子有差异,即用S波计算的场地放大响应要明显大于用脉动计算的场地响应。

| Abstract: | In this paper, three strong motion station＇s site responses are calculated by the H/V spectral ratio method based on strong motion data recorded by Anhui strong motion network. The site response spectra of ground microtremor and S wave are consistent in general for basement rock site of thinoverburden site. However, for thick overburden site over 30.5 meters, both spectral ratio curves are obvious different, which means that the site response spectra calculated by ground microtremor is much bigger than that calculated by S wave. |
