Abstract The Yangpeng tunnel in Northern Guangdong province on the expressway from Beijing to Zhuhai was investigated for the in-situ detection and recognition of the characteristics,the sizes and the specific locations of concealed structural damages(defects) of the carbonate rocks using the technologies of electromagnetic wave perspective imaging between holes and Color-CT tomography imaging. The results from the electromagnetic wave perspective imaging between holes and the Color-CT tomography imaging suggest that the fracture of the fine structural damage in the carbonate rocks is the minimum recognition units. The minimum recognition units are developed into karst tunnels linking the deep rock surface,and thus leading the geological disasters of ground collapse and inrushing of water and mud in the tunnel.
