How to overcome the urban interference, especially to suppress day and night traffic vibratory noise in underlying Xi'an ground fissure exploration has been a difficult problem for shallow seismic prospecting in engineering purpose.Based on in Xi'an Metro Line 6 engineering, we try to use large tonnage vehicle-mounted vibrator source to suppress strong traffic noise, and wish to determine the location and extension of Xi'an ground fissure in information blank area with seismic reflection prospecting.Through the research works, we draw the following conclusion.Large tonnage vehicle-mounted vibrator source can effectively suppress the urban traffic noise and subsurface reflection horizons information can be obtained accurately.Seismic exploration has high credibility to determine Xi'an ground fissure.The locations determined by the seismic exploration coincide with those determined by the geological drilling very well.Using large tonnage vehicle-mounted vibrator source in prospecting underlying Xi'an ground fissure is feasible.
