GENERALIZED CYCLIC-DEGRADATION-PORE-PRESSURE GENERATION MODEL FOR CLAYS

This paper proposes a model for the behavior of fully saturated normally consolidated and overconsolidated marine clays subjected to uniform cyclic strain-controlled and staged cyclic loading under simple shear conditions. To simulate a clay response similar to that occurring during the irregular cyclic loading of earthquakes, ocean storms, and other natural phenomena, staged cyclic testing with several levels of different uniform cyclic strains was performed. Cyclic degradation, cyclic pore-water pressure generation, and cyclic threshold shear strain were incorporated into the model. Cyclic threshold shear strain was defined as the cyclic strain amplitude below which neither significant pressure develops nor significant degradation occurs. The model was verified by staged cyclic direct simple shear testing of five marine clays. Practical applications of the model are discussed.
