摘要
影响孔隙水压力的因素主要包括总平均应力、广义剪应力和应力洛德角。在总结了前人对孔隙水压力系数的研基础上,推导了基于统一硬化模型的孔隙水压力系数,采用变换应力的方法可以使该模型实现三维化,因此,新的孔隙水压力系数能反映上述3因素的变化对孔隙水压力的影响。
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.
