Application of GV3 in tunnel lining detection
Groundvue 3, a kind of ground-penetrating radar, is newly introduced from Utsi Electronics Corporation in the United Kingdom. The antenna frequency range is from 250MHz to 4GHz. GV3, integrated with transmitter and receiver, is of high efficiency, and also supports multi-channel simultaneous detection, real-time recording GPS/Total Station data. And its instrumentation is lightweight, and is easy to operate as well as user-friendly. Moreover, the corresponding data processing software Reflexw has powerful function of information processing and explaining. In this article, working principle and system composition of GV3 are introduced firstly, which mainly express the depth calculation of target. Then through the test measurement of model and related sites, the evaluation of basic performances of GV3 is given, such as anti-interference, stability and effective depth. At last, an engineering project of Lan Yu railway tunnel detection with GV3 is chosen to verify its effects in the field environment and make sure whether the detection results with GV3 can be used as references for the tunnel quality detection.
