Monitoring stress changes in a concrete bridge with coda wave interferometry

Stähler, Simon, Ernst Niederleithinger, and Christoph Sens-Schönfelder (2011), Monitoring stress changes in a concrete bridge with coda wave interferometry, Journal of the Acoustical Society of America, 129(4), 1945–1952, doi:10.1121/1.3553226.

Abstract
Coda wave interferometry is a recent analysis method now widely used in seismology. It uses the increased sensitivity of multiply scattered sonic waves with long traveltimes for monitoring weak changes in a medium. While its application for structural monitoring has been shown to work under laboratory conditions, the usability on a real structure had yet to be proven. This article presents experiments on a concrete bridge during construction. The results show that small velocity perturbations induced by a changing stress state in the structure can be determined even under adverse conditions. Theoretical estimations based on the stress calculations by the structural engineers are in good agreement with the measured velocity variations.
