EXPERIMENTAL VERIFICATION OF MULTIPLE CORRELATIONS BETWEEN THE SOIL YOUNG MODULUS AND THEIR IDENTIFICATION PARAMETERS

This paper consists to verify the validation of two multiple correlations between the Young's modulus (E) of a soil and its identification parameters. These correlations are used to calculate two types of theoretical moduli called ESIKALI and ELCPC. The exploitation of triaxial test results allows specifying 4 experimental moduli such as the initial modulus Et0, the equivalent modulus Eelq, the secant modulus at 1/2 and 1/3 of the breaking strain Esec1/2 and Esec1/3. Our approach compares the theoretical and experimental modulus through straight linear regressions. The results show that the ELCPC better represents Et0 and Eelq while the ESIKALI is more consistent with Esec1/2.
