The Effectiveness Analysis of Integrative Geophysical Methods on Detecting the Artificial Cavity

With more and more accuracy demands for detecting artificial cavity, unitary geophysical method couldn’t meet the requirement of high-resolution detecting. In this paper, we take one underground artificial cavity as an example, by comparing and analyzing the results obtained from magnetic, DC electric and seismic method, demonstrate how to choose the geophysical methods to detect such type of underground artificial cavity. Our research would give instructions to the later construction.
