APPLICATION OF GEOPHYSICAL TECHNIQUES TO THE NON-DESTRUCTIVE TESTING OF TUNNELS

APPLICATION DES METHODES GEOPHYSIQUES A L'AUSCULTATION DES TUNNELS

TO STUDY THE POSSIBILITY OF APPLYING GEOPHYSICAL METHODS TO THE NON-DESTRUCTIVE TESTING OF TUNNELS, BY MEANS OF MONO- AND MULTI-TRACERS. EMPHASIS WILL BE LAID ON THE APPLICATION OF THESE METHODS TO THE DETERMINATION OF DECOMPRESSED ZONES AND TO THE EVOLUTION IN THE MECHANICAL CHARACTERISTICS OF LININGS.
