Abstract
Electrical resistivity tomography(ERT) method was used to detect air-raid shelters, and 2-D resistivity tomography clearly shows their locations and depths. Meanwhile, high-precision magnetic survey was carried out to improve the reliability of exploration and outline the elongation of the air-raid shelter. The two geophysical methods were integrately applied in the detection of the air-raid shelter under the campus of University of Science and Technology of China, with very satisfactory results.
