摘    要:基于单次散射模型的尾波动功率谱分析法,利用西昌遥测台网地震波实时处理系统记录的24个地震数字化波形资料,计算了西昌地区地球介质对应于13个不同的QC值,在1.0-20.0Hz频率范围内,以幂函数QC=QCf^n拟合QC值随的变化关系,其中Q0值在43.0-82.4之间,n值在0.24-0.94之间,平均值分别为66.2和0.53。

关 键 词:西昌地区  频率依赖性  尾波衰减  Q值  地震波

Abstract:Based on the single scattering model of coda power spectrum analysis,digital waveform data of 24 events recorded by the realtime processing system of the Xichang telemetry network are analyzed to estimate the Q C values of earth medium beneath the Xichang area for 13 specified frequencies.In the range of 1 0 to 20 0 Hz,taking the form of Q C=Q 0f n to estimate the frequency dependency of Q C ,it is found that Q 0 ranges from 43 0 to 82 4,and n from 0 24 to 0 96.The average value of Q 0 and are 66 2 and 0 53 respectively.
Keywords:Xichang area  Coda  Q    frequency dependency
