Influence of frequency range of surface waves on estimation of parameters of heterogeneous concrete using non-contact method

Résumé

This work is focused on studies of influence of selection of the frequency range of dispersion curves of surface waves on efficiency of estimation of the bulk elastic wave velocities and thickness of layers of non-homogeneous concrete. The experimental data comes from non-contact ultrasonic method and estimation of material properties uses optimization procedures. As the model the Thomson- Haskel theory of propagation of surface waves in layered media is used. The model predicts dispersion relationships of pseudo Rayleigh waves. The experimental dispersion curves are obtained by using the Slant-Stack transform. Quality of estimation was assessed based on analysis of fitting of dispersion curves and evaluation of the estimation error of the thickness of the top layers and the velocity of transverse waves for the individual layers.
