| 摘 要： | 用H/V谱比法,计算给出了云南区域数字地震台网23个子台S波随频率变化的台站场地响应特征。结果表明:在1～10Hz频段内,23个子台S波的场地响应相对较平坦,在1.41～2.91之间变化,平均2.08;在大于10Hz的高频段,部分台站的场地响应有较明显的放大。

| Abstract: | To learn the site response characteristics at 23 stations of Yunnan Regional Digital Seismic Network,we used H/V spectral ratios method to calculate the site response changing with the frequency of S-wave at each station.The result indicates that the S-wave site response is relatively smooth in the frequency of 1-10 Hz,varies between 1.41 and 2.91,and the average is 2.08.However,the site responses of some stations are obviously magnified in the high-frequency segment more than 10 Hz. |
