【摘要】 分析新疆乌恰两次5.1级地震4个强震台的强震动记录,第1次地震4个台记录卓越频率在4.25 Hz—13.59 Hz;第2次地震4个台记录卓越频率为2.45 Hz—3.61 Hz。从谱比曲线可以看出,2次地震在同一观测场地的场地效应基本相似,基岩台场地效应在高频部分有明显放大作用,土层场地在高频部分有明显的减小作用。

【Abstract】 In this paper we analysis acceleration records of two M_s 5.1 earthquakes in Wuqia recorded by four strong motion stations. We found that primary frequency of the first earthquake is 4. 25 Hz to 13. 59 Hz, and primary frequency of the second earthquake is 2. 45 Hz to 3. 61 Hz. From the curve of spectrum, we find that the curves of two earthquakes spectrum are basically similar on the same site and the field effect of high frequency is obviously enlarged on rock site, and is obviously decreased on soil site.
