WAVES SPECTRAL AND CORRELATION ANALYSIS APPLICATION FOR GROUND DYNAMIC PARAMETERS DETERMINATION.

Assessment of soil dynamic parameters via wave propagation method utilizing results of elastic or viscos-elastic wave analysis. In this paper is only outlining the basic of the theoretical subject which is necessary for experimental applications via impulse-seismic methods (ISM) or the phase velocity method. The ISM experimental study of ground stress-wave propagation permits the ground to be modelled as a damped, viscoelastic half space. The viscoelastic model of soil simulation using the complex modulus conception, offers a very good approach to the actual soil behavior. The paper also presents the experimental ISM tests procedure in-situ and results obtained by correlation and spectral analysis application. [ABSTRACT FROM AUTHOR]
