dc.description.abstractNowadays, many environmental and climatic factors such as weathering actions, temperature variation, chemical attacks, abrasion and other degradation processes can cause near surface damage (0.0 m to 0.5 m) to most concrete structures exposed to severe environmental conditions. As such, the spread of such damage and, subsequently, the loss of mechanical properties of materials are very progressive in long term. The main purpose of Multichannel Analysis of Surface Waves (MASW) method is to 1) characterize near surface damage in concrete structures as a nondestructive testing procedure, 2) estimate the thickness of superficial layers and determine shear-wave velocity (V[subscript S]) profiles. The originality of this research is the application of MASW as a non-destructive method for the evaluation of near surface damage in concrete structures. Indeed, major applications of this method are concerning geotechnical applications. Experiments have been conducted on two concrete slabs (0.80 m, 3 m et 3.50 m) at IREQ with different typical simulated near surface pathologies in order to test the accuracy of MASW method. The results demonstrate that the MASW method has a potential to identify the homogeneity of concrete and estimate the thickness of superficial layers in concrete structures.fr
