The utility model discloses a city ground shallow layer seismic detection device has solved the backing plate device as the big problem low with surveying the rate of accuracy of noise jamming that arouses the ground roll seismic source to exist. Including seismic detector (3) and wave detector (4), be provided with the seismic source and arouse cylinder (2) on ground (1), seismic detector (3) arouse cylinder (2) to link together through source signal line and seismic source, and seismic detector (3) link together through rectified signal line and wave detector (4). The utility model discloses site operation easy operation, it is high to survey the rate of accuracy, is particularly suitable for surveying the city ground.
