Ground Penetrating Radar (GPR) is a high efficiency technology to detect the cylindrical medium in the concretes material. The electromagnetic wave is incidental to double-rebar, and measures the reflection signal behaviors from energy zone. The results from the reflection signal of electromagnetic wave of the reinforcement concretes allow evaluating the radius of double-bar (1.6cm, 1cm). A physical model can effectively measure the radius of double-bar by the result of electromagnetic wave reflex behavior analysis. The results indicate that, this techology is capable of estimating the reinforcing double-bar radius to within 6%.

Because of High-resolution, high accuracy, rapid and efficient, Ground-penetrating radar has been widely used in engineering testing as one of non-destructive evaluation (NDE) methods. Combined with practical work, this paper introduced how to use the ground-penetrating radar in tunnel liner testing, the detection, preferences and waveform analysis, etc.
