One of；Tenth exciting point selection be located at tunnel right wall, four meters away from face, be ground away from ground level to tunnel top height
1/8th；11st exciting point selection be located at tunnel right wall, four meters away from face, be ground away from ground level to tunnel
High a quarter at the top of road；12nd exciting point selection be located at tunnel right wall, four meters away from face, away from ground level be
Ground to tunnel top it is high 1/2nd；
Step B) vibrations are excited in each impacting point respectively using exciting device, while triggering is arranged on all vibration letters in tunnel
Number reception device and wireless data acquisition device synchronous acquisition vibration signal；
Step C) shock wave that excites of exciting device is directly by first vibration signal reception device, and by first wireless data
Harvester is collected；The shock wave is directly received by wireless data storage device simultaneously, and using this signal as trigger signal
Synchronously trigger second and third, four, five, six, seven, eight, nine, ten, 11 wireless data acquisition devices start collection；
Step D) every time excite shock wave encounter in communication process front impedance interface when can reflect, reflect, diffraction, this
A little holographic signals for exciting shock wave to propagate in the non-excavation section in tunnel all can by second and third, four, five, six, seven, eight, nine, ten, ten
One vibration signal reception device is received, and is collected by each corresponding wireless data acquisition device；
Step E) holographic signal collected is wirelessly sent to wireless data by each wireless data acquisition device again
Storage device；
Step F) wireless data storage device again by all data received by 802.11Nwifi modes be sent to control eventually
End；
Step G) control terminal is analyzed and processed after receiving whole vibration signal data, and drafting and generation tunnel are not excavated
The hologram three-dimensional image and image of the geologic structure of section.
