地质雷达在道路质量与病害检测中的应用

Application of GPR in road quality and disease detection

随着我国公路及市政道路的快速发展,建设规模与里程的逐渐增多,使得道路网密度进一步升高,人们也加强了对道路工程质量检测的重视。地质雷达作为目前应用比较广泛的一种连续的、高分辨率的、高精度的无损检测方式,应用在建设工程质量检测各个领域,在道路工程质量与病害异常体检测中取得了很好的效果。基于此,主要探究了地质雷达技术的原理特点,并提出了该技术道路工程中的实际运用。最后,结合工程实践,从检测流程、数据分析及结果等角度,提出了地质雷达技术在实际中的具体运用,同时还对地质雷达检测结果与钻芯法进行验证分析,验证了地质雷达检测的可靠性与准确性。

With the rapid development of highway and municipal roads in China, the scale and mileage of construction gradually increase, which makes the road network density further increase, and people pay more attention to the quality testing of road engineering. As a kind of continuous, high resolution and high precision nondestructive testing method, GPR is widely used in various fields of construction engineering quality detection, and has been well used in road engineering quality and abnormal body detection. Based on this, this paper mainly explores the principle and characteristics of geological radar technology, and puts forward the practical application of this technology in road engineering. Finally, combined with the engineering practice, detection process, data analysis and results, this paper puts forward the specific application of GPR technology in practice, and also verifies the reliability and accuracy of GPR detection through the verification and analysis of GPR detection results and drilling core method.
