In engineering application, the most effective solution is to adopt an advanced geological detection technology to detect the geological conditions in front of a working face in advance, particularly poor geologic bodies such as faults, broken zones and the like, so that reasonable treatment measures and construction plans can be made in advance. The seismic wave advanced prediction method is used for detecting a possible bad geologic body in front of a tunnel face in the tunnel construction process, seismic waves are excited on the side wall of a tunnel, when the seismic waves meet the interface of the bad geologic body, a part of signals are reflected back and received by a seismic sensor (geophone) arranged on the side wall, and the geological condition in front of the tunnel face of the tunnel is known through processing and analyzing the reflected signals.
