The invention provides a land anti-seismic suitability monitoring device based on a GIS technology. The land anti-seismic suitability monitoring device comprises a base with a circular ring shape, wherein a plurality of uniformly-distributed stand columns are fixedly arranged at the part, close to outer periphery, of the top the base; the side part of each stand column is provided with an internalthread sleeve; a plurality of the internal thread sleeves are uniformly distributed with the central axis of the base as a center; and each internal thread sleeve is fixedly connected with one corresponding stand column through a first support. The land anti-seismic suitability monitoring device provided by the invention has simple and ingenious structure, can complete power supply during drilling through a plurality of motors of the same model, realizes pre-drilling through a plurality of threaded drill rods which have larger drilling power to a soil layer compared with drill pipes, can moreeasily drill into the ground, and protects core components like the drill pipes; a drill bit can be conveniently replaced after damage; the efficiency of drilling is improved through the arrangementof combined drilling; and the device can rapidly detect the soil layer, and is convenient and highly-efficient.
