| Abstract: | Because of particular features of high resolution, high efficiency and non-destructive inspection, the geologic radar technique can be used in advancing geologic predicting operations. In tunnel construction, the method can correctly predict rock body structure and unfavorable geologic bodies in front of working face. Effectively detect usual problems in tunnel concrete lining such as: defects on liner and surrounding rock copula, local fissure, liner thickness insufficiency, cavity between liner and rock, insufficient backfilling and water-rich zone. |

| Keywords: | dielectric constant working face lining non-destructive inspection geologic radar |
