摘要
本文简要概述了探地雷达的应用现状,阐述了在城市道路病害检测中基于探地雷达法的干扰源图像建立和特征分析的重要性。介绍了探地雷达法的工作原理,根据实际工程资料,总结了城市道路病害检测中常见的干扰源类型及其特征图像,分别对不同种类的干扰源在探地雷达图像上的电磁波传播特征进行了详细分析,提出了采用探地雷达物探技术进行城市道路病害检测时削弱干扰的有效手段。
This paper briefly generalizes the theory and application status of GPR（Groud Penetrating Radar）,and describes the importance of common interference image establishment and its corresponding electromagnetic wave propagation characteristic analysis.Through practical engineering projects it sums up the type and image characteristic of common interference in routine road detection,and analyzes the electromagnetic wave propagation characteristic of the interference,then proposed some effective means of reducing interference.
