摘要

地下公用设施是指服务或公用设施提供商使用的任何地下线路、装置或结构。地下公用设施检查是对需要检查的指定区域进行详细检查的过程。检查的目的是确保地下公用设施状况良好,并检查是否有任何故障。通过使用地面穿透雷达 (GPR),该技术可以利用无线电波捕捉地表以下的图像。我们利用以往参考文献中的各种数据来讨论和分析 GPR 在地下公用设施检测中的能力,以确保其在检测中发挥最佳性能。GPR 技术已成为定位地下公用设施、防止施工项目中的损坏和事故的重要工具。本文探讨了 GPR 技术的各种进步,包括数据处理方法和扫描技术,以提高地下公用设施测绘的准确性和有效性。本文介绍的研究突出了 GPR 检测地下公用设施的能力。本项目中使用的 GPR 数据收集自马来西亚核机构的评估与验证设施 (EVF)。GPR 数据验证了这些预测位置的准确性,并与承包商提供的竣工图纸进行了比较。此外,还讨论了在不满足最佳条件时可用于提高 GPR 精度的替代分析方法。

Underground utility inspection using ground penetrating radar
Underground utility refers to any below-ground line, installation, or structure used by a service or utility provider. Underground utility inspection is a process of examining the designated area that needs to be inspected in detail. The purpose of the inspection is to ensure that the underground utility is in good condition and to check for any faults. By using the ground penetrating radar (GPR), the technology can capture images below the surface of the ground using radio waves. The various data through previous references are used to discuss and analyse the capability of GPR for underground utility inspection to ensure its gives the best performance for the inspection. GPR technology has become an essential tool for locating buried utilities and preventing damage and accidents during construction projects. This paper explores various advancements in GPR technology, including data processing methods and scanning techniques, to improve the accuracy and effectiveness of underground utility mapping. The research presented in this paper highlights the abilities of GPR to inspect underground utilities. The GPR data used in this project was collected from the evaluation and verification facility (EVF) in the Malaysia Nuclear Agency. The accuracy of these predicted positions was validated from GPR data and compared with as-built drawings from the contractor. The alternative analysis approaches that could be applied to improve the GPR accuracy when the optimum conditions are not met are also discussed.
