GPR analysis to detect subsidence: a case study on a loaded reinforced concrete pavement

Subsidence seriously affects the structural stability and safety of pavements foundation soils. In heavy-loaded pavements, there is a risk floor sinking further construction collapse; hence, need to develop efficient methodologies detect subsidence earlier. This work proposes use ground penetrating radar (GPR) as solution non-invasively inspect subsoil. Furthermore, interpretation GPR data arguably subjective highly dependent on who interprets it, different imaging techniques are herein exploited improve interpretability detection settlement phenomena. The approach was applied heavily loaded reinforced concrete pavement servicing manufacturing facility. Amplitude- texture-based methods were used subsidence. such validated with additional geotechnical studies, which show that proposed provide reliable results good agreement between techniques.
