| 摘 要： | 利用2008年10月5日新疆乌恰6.8级地震时新疆强震动观测台记录的S波资料和脉动观测资料,采用Nakamura方法计算了这些强震观测台的场地响应.结果表明:(1)地震记录前10 s的脉动场地响应明显大于测试脉动和地震记录S波的场地响应,是测试脉动和记录S波场地响应的3倍,而测试脉动场地响应和S波记录场地响应基本相符....

| Abstract: | Selecting the records of the seismic microtremor before the MS6.8 Wuqia earthquake on october 5,2008 and the S-wave data of the earthquake recorded by Xinjiang Strong Motion Network,we calculate the response of the strong-motion at these 26 stations through the Nakamura's technique.The results are as the following:(1)Ten seconds before the P-wave,the site amplification effects of the Earth pulse are 3 times of the effects of S-wave and the effects of the testing pulsation.Meanwhile,the site amplification ef... |
