Abstract:

As one of the most commonly used long-term geological forecasting methods,  theTSP advanced geological prediction system, is now used successfully in many tunnels at home and aboard, which plays a tremendous role in tunnel construction and geological prediction. A variety of surrounding rock and site conditions will be encountered in the collection process of the TSP data, so the collections of the original seismic waveforms are different in many ways. Research was made  on the characteristics and causes of several common abnormal original waveforms. By adopting corresponding measures, it can  avoid  triggering and accepting abnormal signals, and more rational seismicwaves can be obtained, and the accuracy and reliability interpretation of the TSP data can be improved.
