摘要: 近年来,城市建设的发展及地下空间的开发利用在为群众生活带来便利的同时,一定程度上也导致了城市道路病害的发生,道路塌陷事故频发促使需要对城市道路进行一次全面的体检。本文基于三维时域有限差分方法原理的GprMax,对地质雷达在充气型管道、方涵、空洞等的传播特性进行了数值模拟,初步建立了雷达图像的正演特征模型,并以三维探地雷达在天津地区的道路检测工作为例,对雷达数据体的图像特征进行分析,同时介绍了城市道路地下病害体检测中的相关经验和应用,为道路检测提供了技术方法和指导。

Abstract: In recent years,the development of urban construction and the development and utilization of underground space have brought convenience to people's lives, but to a certain extent, it has also led to the occurrence of urban road hazard, and the frequent occurrence of road collapse accidents has prompted us to conduct a comprehensive physical examination of urban roads.In this paper, the propagation characteristics of geo-radar in media such as pipe, culvert and cavity are numerically simulated based on GprMax, which is based on the principle of 3D finite-difference time-domain method.A preliminary forwardmodeling of radar images is established and the image characteristics of radar data bodies are analysed using the example of 3D ground-penetrating radar in road detection work in Tianjin area, while relevant experiences and practices in the detection of urban road subsurface hazardare are introduced,Which provide technical methods and guidance for road detection.

Key words: GprMax, 3D ground-penetrating radar, road detection, application
