摘要
利用"十五"数字网络项目兰州宽频带地震台网资料,对甘肃华亭地区矿震记录波形采取多种数据处理技术,剔除噪声干扰、滤波后,分析解释了甘肃华亭矿震的典型记录特征。结果表明:华亭矿震的宽频带记录表现为近台记录大周期面波发育,持续时间较长;平凉台(PLT)场地放大作用明显,所计算的震级偏大。
Based on the data of Lanzhou digital seismic broadband network,after getting rid of noise and wave filtering by using some data processing techniques,the typical record characteristics of mining-induced earthquakes in Huating mine area,eastern Gansu province,are analysed and interpreted.The result shows that in the records of mining-induced earthquakes,the large period surface wave from close stations is significant and the last time is longger.At Pingliang station,caused by site response amplifing the magnitudes are obviously bigger than other stations.
