Abstract
AbstractA reliable estimate of secant undrained Young’s modulus (Eu) is necessary to quantify the undrained settlement of structures underlain by fine-grained soils. A large number of CK0UC triaxial tests have been carried out on eight resedimented clays to establish the effects of soil composition, applied shear stress, overconsolidation, and vertical consolidation stress on the magnitude of Eu. These tests were performed at effective stresses ranging from 0.02 to 100 MPa. Low plasticity soils tend to have a higher Eu compared with high plasticity soils. The effect of composition diminishes as the applied shear stress increases. Overconsolidated (OC) soil has a higher undrained modulus than normally consolidated (NC) soil, though a change in the overconsolidation ratio of OC soil does not have a significant effect on Eu. Regression analyses performed on the experimental data define relationships for Eu as a function of stress level for both NC and OC soil.
