Abstract

As the complexity of underground infrastructure increases, the demand for accurate non-destructive underground exploration grows. Ground Penetrating Radar (GPR) is commonly used for such explorations; however, its effectiveness is limited beyond depths of approximately 1 m due to significant electromagnetic wave attenuation. This study aims to surpass these depth limitations by employing seismic waves for precise location estimation of buried pipes. Real-scale experiments were conducted on sites with pipes buried at depths 1.5 m and 2.5 m, demonstrating the effectiveness of our proposed method. We introduced a signal and image processing algorithm, enhanced integrating ridge detection and template matching, for more accurate buried pipe location estimation. Results revealed that the locations of buried pipes could be estimated with an error margin of less than 0.2 m. Furthermore, our approach not only enables objective visualization of survey results but also suggests a reduction in the number of sensors required compared to traditional expert visual inspections.
利用浅层地震反射技术确定深埋管道的位置
随着地下基础设施复杂性的增加,对精确无损地下勘探的需求日益增长。探地雷达(GPR)通常用于此类勘探;然而,由于显著的电磁波衰减,其有效性在大约1米深度以外受到限制。本研究旨在超越这些深度限制,利用地震波来精确估计埋地管道的位置。在埋管深度分别为1.5 m和2.5 m的现场进行了实测实验,验证了本文方法的有效性。引入了一种信号和图像处理算法,增强了脊线检测和模板匹配的集成,以更准确地估计地埋管的位置。结果表明,该方法能够准确估计埋管位置,误差范围小于0.2 m。此外,我们的方法不仅可以实现调查结果的客观可视化,而且与传统的专家视觉检查相比,还可以减少所需的传感器数量。
