Abstract: The effects of compaction conditions, density and water content, and pre-compression stress history on dynamic strength and deformation properties, modulus of rigidity (G) and damping factor (h), of compacted cohesive soils were investigated through cyclic triaxial tests, and discussions were made on their use in evaluating seismic failure and slope stability of earthfills. A few conventional practical formulae were proposed in these element tests of estimating the undrained cyclic strength and the dynamic modulus of rigidity through ordinary static compressive strength and deformation modulus. FEM dynamic response analysis was then conducted for a model earthfill to know pre-compression effects on the response behavior, distribution of rigidity and local stability factor, in the evaluation of seismic slope failure.
