【摘要】 通过描述列车振动作为震源所产生地震波的采集方法,对大秦铁路线怀柔段以及京沪铁路线兖州段铁路沿线的两次观测试验记录进行了观测系统和信号品质的比较研究,分析了通过宽频地震仪和浅层地震仪所接收火车振动信号的不同特点,为再次开展野外信号采集提出了建议,并预言列车振动将成为铁路沿线进行浅层地震勘探生产中的有效震源。更多还原

【Abstract】 Through describing the seismic wave gathering method about the source of the vibration induced by trains, the two observation records, gathered at Huairou segment, Da-qin track line, and Yanzhou segment, Jing-hu trace line, are compared on the geometry and the quality of gathered signals. Analysis give out the different characteristics of signals gathered through the broadband seismographs and the shallow layer seismographs, and the suggestions to the next field signal gathering examination have been made. At last, the source of the vibration induced by trains were regarded as a intending source that will be used in shallow layer seismic exploration along the rail line.更多还原
