| 摘 要： | 采用Nakamura方法,利用2007年6月3日宁洱地震强震动记录S波资料和脉动观测资料,计算了宁洱震区一些强震动台的场地响应.结果表明,当台站场地为基岩或覆盖层较薄时,由脉动数据和S波数据分别计算的谱比曲线一致性很好.当覆盖层大于35 m的时候,两者的谱比值有差异,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,we calculate the strong motion site responses by the Nakamura method based on the pre-seismic microtremor and S wave data recorded during Ning'er earthquake on 3 June 2007.The site response spectra of microtremor and S wave are consistent in general for basement rock site or thin-overburden site.However,for thick-overburden site over 35 meters,both spectral ratio curves have obvious differences,which means that the site response spectra calculated by ground micro-tremor is much bigger than tha... |
