GPR has been widely acknowledged as an effective and efficient technique for imaging the subsurface. But the process of constructing 3D GPR images (C-scans) is still subjective and mainly relies upon the operator's knowledge and experience. This stud

Field validation of water‐pipe leakage detection through spatial and time‐lapse analysis of GPR wave velocity

Autor: Wallace W.L. Lai, Bella Wei-Yat Cheung

Publikováno v: Near Surface Geophysics. 17:231-246

Detection of leakage in a buried water pipe is a crucial issue, as underground pipes become aged and these pipes are often used as pathways for aggressive chemical agents. Non‐destructive geophysical methods for identifying such underground leakage

Imaging and condition diagnosis of underground sewer liners via active and passive infrared thermography: A case study in Singapore

Autor: Wing Chan, Chee Lin Koh, Janet F.C. Sham, Wallace W.L. Lai

Publikováno v: Tunnelling and Underground Space Technology. 84:440-450

This paper presents a case study of customizing an in-house built In-pipe Infrared Thermographic System (IPITS), which makes use of thermo-images for imaging and diagnosis of pipe crown condition in underground sewer pipelines. Active and passive inf

Underground Utilities Imaging and Diagnosis

Autor: Wallace W.L. Lai

Publikováno v: Urban Informatics ISBN: 9789811589829

The invisible and congested world of underground utilities (UU) is an indispensable mystery to the general public because their existence is invisible until problems happen. Their growth aligns with the continuous development of cities and the ever-i
