唐山地区尾波Qc值研究

STUDY ON THE QC VALUE OF CODA IN TANGSHAN REGION

  • 摘要: 利用首都圈地震数字台网资料,计算了唐山地区不同尾波窗长的Qc值。尾波窗长为15~30s时,Qc(f)=53f1.1;尾波窗长为30~60s时,Qc(f)=256f0.8;尾波窗长为60~90s时,Qc(f)=304f0.72;尾波窗长为90~120s时,Qc(f)=2400.68。可以看出,同一地点的Q0值随尾波窗长的增加而增大,但尾波窗长为90~120s时,Q0反而减小。

     

    Abstract: The QC values of different coda in Tangshan region are calculated with the data recorded by digital seismic network in Capital area.The results show that,when the length of coda window is at 15~30 seconds,QC(f)=53f1.1;when the length of coda window is at 30~60 seconds,QC(f)=256f0.8;when the length of coda window is at 60~90 seconds;QC(f)=304f0.72,when the length of coda window is at 90~120 seconds QC(f)=240f0.68.It is concluded that Q0 increases with the length of coda window,but reduces when the length is 90~120 seconds.
