| Zusammenfassung: | The invention discloses an underground tunnel directional geophysical prospecting method, and belongs to the technical field of tunnel detection. The directional geophysical prospecting method for the underground tunnel comprises the steps that S01, the trend of the underground tunnel and a construction site are determined, the construction site is far away from an area where a ground building above a pre-detected tunnel is located, and finally a preset drilling track and a construction target azimuth angle are determined; s02, after the drill hole is communicated with the tunnel, the geophysical prospecting equipment is pushed into the drill hole through high-pressure water flow until the geophysical prospecting equipment enters the pre-detected tunnel; and S03, current is introduced into the surrounding medium through geophysical prospecting equipment to generate an electric field, and the distribution characteristics of the electric field in the surrounding medium are measured, so that the electrical resis |
