【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。更多还原

【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 micro-tremor and S wave are consistent in general for basement rock site of thin-overburden 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 micro-tremor is much bigger than that calculated by S wave.更多还原
