Correction Method of Mileage Deviation in Tunnel Concrete Lining Detection by Ground Penetrating Radar
(1 China Railway Northwest Research Institute Co., Ltd., Lanzhou730070;
2 Anhui Polytechnic University College of Architecture and Engineering, Wuhu, 241000)
Abstract Regarding the mileage deviation caused by speed difference of the antenna or untimely mileage marking by the detector during tunnel lining detecting by ground penetrating radar, a mathematic model to illustrate the relationship between the detected mileage and actual mileage is established. This model can be used for mileage correction and to improve the accuracy of detection.
