CYCLIC PORE PRESSURES UNDER ANISOTROPIC CONDITIONS

A significant factor in seismic stability studies of slopes and dams of cohesionless materials is the development of pore-water pressures under the complicated stress conditions acting on potential failure surfaces during an earthquake. The stress conditions are represented by consolidation under anisotropic stress conditions, static shear stresses on potential failure planes and cyclic stresses representative of the earthquake loading. Using data from an extensive program of cyclic triaxial tests it has been possible to describe analyitically with satisfactory accuracy the pore-water pressures due to cyclic loading as a function of the anisotropic consolidation stress ratio, Kc, the cyclic shear stress ratio, and the number of load cycles. The function describing the development of pore-water pressure greatly facilitates the computer analysis of the stability of slopes under cyclic loading. /Author/
