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. Key words: electrical resistivity tomography; high-precision magnetic survey; air-raid shelter; integrated geophysics
