Pier shaft of a Toulouse Metro Line C viaduct with step-frequency GPR

Pier shaft of a Toulouse Metro Line C viaduct with step-frequency GPR

Description

Survey of the shaft of a pier on the viaduct of the future Line C of the Toulouse Metro, in Labège (Haute-Garonne, France). This prestressed concrete railway structure was in its finishing phase in October 2026. The reinforced concrete shaft has a circular cross-section 2 m in diameter. Profiles were collected directly on its curved face with the GSSI FLEX NX, a step-frequency radar. The radargrams show the reinforcement of the shaft and allow the concrete cover to be estimated. The dataset can be used to practise rebar picking on a new bridge structure, to observe how a convex surface affects antenna coupling, or to plan coring or anchoring away from the steel. Raw files in GSSI native format (.DZT).
