摘要
利用目前各类仿真记录的震级计算公式及近年金寨地震台台基的地动噪声有效值,结合各区域震相识别经验等设定了可检测地震的首至P波震相振幅、S波和面波的最大振幅与台基地动噪声有效值的比值,并分别计算和分析了金寨台宽频带数字地震仪仿短周期(DD-1仪)记录的近震监测能力、仿中长周期记录的远震监测能力及仿长周期(763仪)记录的远震和极远震监测能力。
The first arrival P wave seismic phase,the maximum amplitude of S wave and surface wave and the effective values of site ground noise are determined by using the magnitude formula of the current various simulation records and the effective values of ground noise of digital seismic site at Jinzhai seismic station in recent years and combing with experience of regional seismic phase identification,etc. The earthquake monitoring capability of simulate short-period( DD-1seismograph),teleseismic monitoring capability of the simulation middle-long period and teleseismic to very distant earthquake monitoring capability of the simulation long period( 763 seismograph) recorded by the very broadband digital seismograph at Jinzhai station are calculate respectively and analyze near in the range of 100 km,1 000 km,130° and the globe.
