摘要
///According to the principle of TGP tunnel geological prediction system and the problem existent in the process of detection,this paper has discussed some abnormal-signal-induced factors such as external pulse signal interference,current interference,poor coupling,pipe wave and charging parameters,and analyzed the cause of resultant errors with the feedback from engineering application.On such a basis,some suggestions were put forward to improving the understanding of anomalous seismic wave and geological work as well as edge diffraction wave for avoiding the abnormal signal generation and reception.
