摘要: 城市道路病害体作为城市安全的重要隐患,具有隐蔽性、突发性等特点,需及时予以检测和处理。地质雷达利用电磁波反射确定地下介质分布,以其无损、快捷及浅层高分辨率优势广泛应用于城市道路病害检测中,但要对病害体作进一步处理,需要对病害体做进一步精细勘测。本文利用地质雷达在道路病害检测中的优势,结合三维测量内窥镜技术的实时视频和测量功能,实现道路地下病害体的准确定位和精准测量,为后续防治和治理提供有用数据。

Abstract: As an important hidden danger of urban safety,urban road diseases has the characteristics of concealment and sudden,which needs to be detected and treated in time. Ground penetrating radar uses electromagnetic wave reflection to determine the distribution of underground media. It is widely used in urban road disease detection because of its nondestructive,fast and shallow high-resolution advantages. However,if the disease body needs to be further treated,it needs to be further carefully surveyed. This paper combines the advantages of ground penetrating radar in road disease detection with the real-time video and measurement function of three-dimensional measuring endoscope technology to realize the accurate positioning and accurate measurement of road underground disease body,so as to provide useful data for subsequent prevention and treatment.

Key words: ground penetrating radar(GPR), 3D measuring endoscope(TDE), road disease body, cavity, spectrum
