摘要

本文介绍了技术解决方案在南非桥梁检测方法领域的应用，旨在提高目前的视觉桥梁检测方法。无人驾驶飞行器(uav)可以作为收集桥梁图像数据的替代方案，并且可以通过使用摄影测量软件从捕获的图像中创建点云模型。在本研究中，作为一种提出的新的检查方法，通过仅使用点云模型和捕获的图像来完成TMH 19桥梁结构检查表。通过对历史检验等级和点云检验等级的比较，研究了新提出的检验方法的有效性和实用性。该研究得出结论，桥梁检查员可以使用新的检查方法识别和评估桥梁结构的关键缺陷，但存在局限性和需要确定的具体用例。

Enhanced methodology for visual bridge inspections in South Africa

This paper introduces the application of technology solutions into the realm of bridge inspection methodologies in South Africa, aiming to enhance the current visual bridge inspection methodology. Unmanned Aerial Vehicles (UAVs) can be used as an alternative to collect bridge image data, and point cloud models can be created from captured images by using photogrammetry software. For this study, accredited bridge inspectors were approached to complete TMH 19 inspection sheets of bridge structures using only the point cloud models and captured images, as a proposed new inspection methodology. This paper compares historic inspection ratings and the point cloud inspection ratings to investigate the effectiveness and practicality of the new proposed inspection methodology. The study concluded that bridge inspectors could identify and rate critical defects of bridge structures using the new inspection methodology, but there are limitations and specific use cases that need to be identified.

期刊介绍： The Journal of the South African Institution of Civil Engineering publishes peer reviewed papers on all aspects of Civil Engineering relevant to Africa. It is an open access, ISI accredited journal, providing authoritative information not only on current developments, but also – through its back issues – giving access to data on established practices and the construction of existing infrastructure. It is published quarterly and is controlled by a Journal Editorial Panel. The forerunner of the South African Institution of Civil Engineering was established in 1903 as a learned society aiming to develop technology and to share knowledge for the development of the day. The minutes of the proceedings of the then Cape Society of Civil Engineers mainly contained technical papers presented at the Society''s meetings. Since then, and throughout its long history, during which time it has undergone several name changes, the organisation has continued to publish technical papers in its monthly publication (magazine), until 1993 when it created a separate journal for the publication of technical papers.
