A method of high efficient ground penetrating radar signal interpretation for tunnel lining disease detection was proposed. This interpreting method had been analyzed and verified with practical engineering. The reinforcement in the image showed crescent shaped, cavity showed arc reflection in the image, non-compaction performances clutter waveform, the antenna was a strip of bright reflection. The interpreting method provides reference and basis for tunnel lining detection which plays an important role in treating tunnel diseases and evaluating tunnel lining quality.
