Dynamic behavior of earth dams containing stratified soils
A model earth dam containing stratified soils, i.e., alternating layers of clay and sand was subjected to base shaking in a 1 m radius centrifuge using a servo-hydraulic shaker. The model dam contained three sand layers, a central clay core, an upstream clay blanket and a downstream berm. Test results acquired during and after base shaking of the above model dam are presented. Triggered by loosening and weakening of sand close to the bottom clay/sand interfaces, model dam failed, in general with layers moving downward and outward from the centerline. A fully coupled dynamic finite element code DYSAC2 and bounding surface plasticity models are used to predict the behavior of the centrifuge model and a reasonable comparison is obtained between the predicted and the measured pore water pressures, accelerations and displacements.
