摘要
探地雷达是利用宽带高频电磁波以脉冲形式来探测地表之下介质内部结构分布规律的一种地球物理方法。它广泛用于灾害地质勘查、岩土工程调查和工程质量检测等众多领域。本文给出了一个在治理城市塌陷区的工程质量检测中的应用实例,通过两种高频天线的探地雷达检测和二维模型正演结果对比,对塌陷区治理质量以及是否存在隐伏塌陷隐患给出了明确的结语。
Ground penetrating radar is a means to detect internal structure and distribution law of underground medium by broadband high-frequency electromagnetic wave, and has been widely applied in many fields such as hazard geology exploration, geotechnical survey and engineering quality inspection. This paper brought an example of the technique used in engineering quality inspection of treatment of city subsidence, by comparison of the detection result of the radar with two high-frequency antennas with 2D model forward modeling result, gave a definite conclusion on the treatment quality and whether a hidden subsidence exists or not.
