Auscultation non-destructive des sous-faces de dalles en beton arme


Pathology of slabs is sometimes induced by cavity situated under the concrete part. The object of these research consists in creating a prototype of a non-destructive auscultation system that could be able to detect quickly and easily such voids . The impulsion technique so-called "impedance mecanique", will be used. The research is divided in 4 distinctives parts: 1) description of the parameters that occur during the data acquisition (for example: accessibility on civil works) and definition of the characteristics of the prototype. Writing of the signal treatment algorithms. 2) creation of the system according to the parameters described in part 1. Writing of a dab acquisition program 3) experimentation in laboratory and on site. Re-writing of the programs to get them easier to use 4) Diffusion of the technique in Europe and writing of recommendation procedures
