Cases of applying geophysical survey investigations such as self-potential prospecting survey, electrical resistivity survey and geothermal survey to evaluate wholesomeness of levee structures or detecting levee' leakage areas are increasing, but such cases are currently restricted to simple applications of geophysical survey technology that assume 2-dimensional structure types. Also, domestic researches that are directly related to the diagnosis of the levee's safety through application of underground radar that has the highest resolution among geophysical surveys is almost non-existent, and cases of applying ground penetrating radar (GPR) survey to the joint investigation of the tunnel lining's rear have been reported. Therefore, this study attempted to effectively comprehend the safety of the levee's basic structures and drainage box-culvert by utilizing 2-dimensional electrical resistivity surveys, expansion of 3-dimensional survey path and GPR surveys.
