Abstract
A simple pore pressure build-up model is introduced in this paper to simulate the effective-stress paths of saturated soils subjected to dynamic loadings. It is a five-parameter model in which two pairs of two parameters are used to define the effective-stress paths during the loading phases of first cycle and post-phase-transformations, respectively, and a dynamic pore pressure parameter is judiciously introduced to represent the increment of pore pressure due to shear loading in between the previous two phases. All parameters can be easily deduced from conventional undrained triaxial tests. Satisfactory results have been achieved for case studies including published results of laboratory uniform and non-uniform cyclic tests and seismic field measurements.
