- 摘要:
- 应用福建地震台网记录的爆破与地震的数字资料，采用波谱分析的方法分析发生在同一区域的爆破与地震波谱特征。结果表明，爆破与地震的拐角频率存在差异，据此得出本区域爆破识别的定量识别判据，为今后爆破的识别提供依据。
Using the digital waveform data of explosion and earthquake by Fujianseismic network, we analyzed the artificial explosion and natural spectrum characteristics of same area by spectrum analysis. It is found out that there are different features in corner frequency between explosion and earthquake records.Based on these features,we gave the the explsion identical criterion, the results provide the basis for explosion identical.
