探地雷达在隧道检测中里程偏差修正方法探讨

摘要

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.%文章针对探地雷达在隧道质量检测中由于天线行走速度不一或检测人员打标记不及时产生的里程偏差,建立了检测里程与实际里程之间关系的数学模型,利用该模型对检测里程进行修正,可使检测结果回归到真实的里程.
