Abstract

Ground penetrating radar (GPR) is regularly applied to examine tunnel liners, roads,railways and runways. Many applications have been pioneering proof-of-concept tests to define the benefits and limitations of GPR. For the quality of tunnel liners major include three parts: (1) the thickness of the liner (2) the Defects of the liner such as the voids , non-compacting area and crack (3) the number, diameter of the rebar and rebar corrosion. There are many situations where GPR signals do contain quantitative information useful for developing data needed for engineering decision making.
