Abstract: The mean total mean stress, deviator stress and Lode’s angle are the three major factors affecting the generation of pore water pressure. The study of the pore water pressure coefficients is summarized. Within the classic elastoplastic theory, new pore water pressure coefficients are deduced based on the Unified Hardening Model, to which the transformed stress tensor is applied. The new coefficients can reflect the above-mentioned effects of the three factors on the pore water generation.

Key words: pore water pressure, SMP criterion, transformed stress, UH Model
