Abstract: The liquefaction model presented in based solely on observed pore pressure responses of sands and was constructed employing some simplifying assumptions. Pore pressure generation of sands under uniform as well as irregular loadings can be simulated by this model. The model requires only a limited number of laboratory tests and a few model parameters. All model parameters can be determined from results of conventional undrained cyclic tests employing uniform stress cycles. Assumptions and performance of this liquefaction model were examined through case studies. This liquefaction model predicted with good accuracy the pore pressure response for both uniform and earthquake-type irregular stress loadings. The model can be incorporated into nonlinear site response methods and soil-structures response methods, and it may be used as a simple alternative to other equally effective, but sophisticated liquefaction models currently available.
