Abstract
We present a pore pressure model that predicts the build-up of residual pore pressure from accumulated shear stress. The main advantage of the model is that all of the input parameters can be selected from a CSR (cyclic stress ratio)- (number of cycles required for liquefaction) curve measured from a stress-controlled test. The formulation of the model and guidelines for selecting its parameters are presented. Comparisons with measurements validated the applicability of the model and also the parameter selection procedure. Further comparisons with another accumulated stress-based model highlight the superiority of the proposed model in terms of accuracy and ease-of-use.
