隧道地震波预报(tunnel seismic prediction,TSP)超前地质预报系统已在国内外多条隧道中成功应用,做为一种应用最为广泛的长距离预报手段,在隧道施工地质预报中发挥了巨大的作用.在TSP数据采集过程中,会遇到复杂多变的围岩和现场条件,采集到的地震波波形也会千差万别.研究了几种常见的异常原始地震波波形特性和成因,并提出采取相应的措施,避免产生和接收异常信号,提高TSP地震波信号质量,为增加TSP数据解译的准确性和可靠性打下坚实的基础.
Tunnel seismic prediction (TSP) advanced geological prediction system has been successfully applied to many domestic and foreign tunnels. As one of the most widely used long-range prediction methods, it has played a significant role in tunnel construction geological prediction. In the process of TSP data acquisition, it encounters complex and variable surrounding rock and on-site conditions, and the waveform of the acquired seismic waves will vary widely.This paper studies the characteristics and causes of several common abnormal primary seismic waveforms and proposes corresponding measures, Avoid the generation and reception of anomaly signals, improve the quality of TSP seismic signals, and lay a solid foundation for increasing the accuracy and reliability of TSP data interpretation.
