Abstract
The stress-dilatancy relations of sand for the stress paths involved in a complete periodic stress cycle are set up. The plastic potential functions for' each loading stage are derived consequently. Based on the idea of using a stress-strain relationship as an alternative strain-hardening law, the drained volume changes under different effective stress paths are derived and verified. A pore pressure generation mechanism which can take into account the dilatancy of soli directly and the related computational model are put forward. The model can calculate the instantaneous and residual pore pressures in sand and depict the liquefaction process of sand quantitatively, especially the dilatancy behavior.
