Dynamic properties of saturated clays are studied considering the effect of changing confining pressure using Stokoe Resonant Column Testing Apparatus. Shear modulus and damping ratio of the mixtures were measured over a strain range of 0.001% up to 0.1%, and then compared with generic nonlinear modulus and damping curves. It is seen that, as the PI increases, the shear modulus increases and damping ratio decreases under same effective stress; as the effective stress increases, the shear modulus increases and damping ratio decreases for the same clay type.<br> Keywords: Clay, Stokoe resonant column testing apparatus.</p> <p class=BareCenter> <a href="http://www.ejge.com/2009/Ppr0913/Ppr0913.pdf" target="_top">Get the entire paper (pdf)</a> &nbsp;&nbsp;&nbsp; <a href="javascript:history.back()">Go back to the TOC</a><br> <a href="http://www.ejge.com/" target="_top"><img src="../../endsign.gif" width="120" height="40" border="0"></a></p> <p>&nbsp;</p> </body> </html>
