Abstract

Non-destructive acoustic testing can be used to find the boundaries and location of contact surfaces of geological layers of solids, fluids and emptiness. Using a suitable device, experiments were carried out for locating the contact surfaces in layered soils and rocks. This search led to information about subsurface geological and geo- technical structures. It was established that the dynamic response of layered structures is characterized by the resulting spectrum and its resonant frequencies. These resonant frequencies correlate to the positions of interlayer contact surfaces and structural disturbances. Values of identified resonant frequencies are used to calculate the P-wave velocities in rock layers and their elastic constants. The results obtained by this prelim
