Anisotropic Behavior of Soils and Pressuremeter Tests.
Abstract
Several important questions related to cavity expansion and pressuremeter testing in clays are being investigated. Tests are performed in a cuboidal shear device to simulate pressuremeter stress paths and to evaluate the strain rate effects. Similarly, experiments will be conducted to evaluate effects of stress relief, relaxation and disturbance. Model pressuremeter tests will be performed in a calibration chamber to confirm the strain rate effects obtained in the cubic triaxial simulation and verify the applicability of the interpretation technique based on anisotropic model to determine the initial in- situ stress. The calibration chamber test equipment is currently being redesigned and modified to perform the model pressuremeter tests. The experimental data will be used to calibrate the anisotropic soil model developed for this study. With this model, one can predict the behavior of clay type material under any desired stress path from the results obtained under a particular stress path, such as the pressuremeter stress path.
