Machine-learning-based ground sink susceptibility evaluation using underground pipeline data in Korean urban area. [PDF]
Ground subsidence caused by natural factors, including groundwater, has been extensively researched. However, there have been few studies on ground sink caused mainly by artifacts, including underground pipelines in urban areas.

Defect Detection and 3D Reconstruction of Complex Urban Underground Pipeline Scenes for Sewer Robots. [PDF]
Detecting defects in complex urban sewer scenes is crucial for urban underground structure health monitoring. However, most image-based sewer defect detection models are complex, have high resource consumption, and fail to provide detailed damage ...

Evolution of Acoustic Pulses in Damaged Underground Pipelines [PDF]
The research is of increasing relevance due to the need for recommendations on improving the existing methods for rapid detection of pipeline damage at the early stages of hydrocarbon liquid flow into the ground through the damaged areas. To detect possible pipeline damage that occurs during the transportation of hydrocarbon liquids, a technique of ...

3D-GPR-RM: A Method for Underground Pipeline Recognition Using 3-Dimensional GPR Images
Ground penetrating radar (GPR), as a non-destructive and rapid detection instrument, has been widely used for underground pipeline detection. However, as the interpretation of 3-dimensional GPR images is still manually performed, the process is ...

Metallography of an Underground Oil Pipeline
The purpose of this article is to show a metallographic analysis of an underground pipeline taken out of operation upon failure. The pipeline had an 8.89 cm (3.5”) diameter and a 7 mm thickness. The study was based on a 45 cm long pipe sample, visibly and entirely corroded, with a fish-mouth crack along its length.
