| 摘 要： | 基于鹤岗地震台阵勘选数据，分析各子台记录的矿震和天然地震的频谱特征，从各子台频谱一致性角度对观测场地进行评估；采用希尔伯特-黄变换（Hilbert-Huang，简称HHT）方法，分析矿震和天然地震的时频特征。结果显示：勘选记录的地震频谱特征与已有研究一致，各子台特征也较一致，该勘选场地适合建设台阵；由经验模态分解（EMD）后的本征模态函数（IMF）分量可以明显识别出矿震面波，矿震和天然地震的HHT谱的时频特征有明显区别。

| Abstract: | Based on the survey data of the Hegang Seismic Array, this paper analyzes spectral characteristics of seismic records for mine earthquakes and natural earthquakes recorded by each observation site and evaluates them from the perspective of spectrum consistency. The HHT method was used to analyze the time-frequency characteristics of seismic records for natural earthquakes and mine earthquakes. The results show that the seismic spectrum characteristics of this survey are consistent with the existing research results and the characteristics of each site are also consistent. The survey site is suitable for a construction site. The surface wave of a mine shock can be clearly identified from the IMF components after EMD. There is a clear difference between HHT spectrum characteristics of seismic records for natural earthquakes and mine earthquakes. |
