摘　　要：该文介绍了在沈阳某区利用三维车载探地雷达成像方法与二维探地雷达成像方法,进行道路综合检测,圈定道路病害体的地下三维空间位置。首先采用三维车载探地雷达进行道路全覆盖普查,根据三维雷达数据圈定病害体大致位置,再利用二维探地雷达垂直病害体的走向进行复测详勘,进一步准确圈定病害体的三维赋存状态。最后,通过钻孔并结合内窥镜观测,确定病害体类型与分布范围,推断病害体成因,科学评估病害体风险等级,及时消除隐患,为道路安全运行提供有力保障。This article introduces the use of 3D vehicle mounted ground penetrating radar imaging method and 2D ground penetrating radar imaging method for comprehensive road detection in a certain area of Shenyang,to delineate the underground 3D spatial location of road disease bodies.Firstly,a 3D vehicle mounted ground penetrating radar is used for road full coverage survey.Based on the 3D radar data,the approximate location of the disease is delineated,and then the vertical direction of the disease is resurveyed by using the 2D ground penetrating radar to further accurately delineate the 3D occurrence status of the disease.Finally,using drilling combined with endoscopic observation to determine the type and distribution range of the disease,infer the cause of the disease,scientifically evaluate the risk level of the disease,timely eliminate the hidden dangers,and provide strong guarantees for road safety operation.
