摘要
在提出剪缩系数概念和修正体积压缩系数概念的基础上,导出了两种轴对称应力状态和一般三向应力状态下孔隙 压力增量与主应力增量关系的理论公式,给出了这三种应力状态下孔隙压力系数的表达式,对这三种应力状态下孔隙压力系 数的关系和变化规律进行了分析,提出了孔隙压力增量与主应力增量关系表达形式的建议。
This paper introduces theoretical equations for the relationship between pore pressure increment and principal stress increment based on the concepts of the shear shrinkage coefficient and the modified volumetric compressibility under two kinds of axial symmetry stress conditions and a general three-directional stress condition. The pore pressure coefficients are then derived for these three conditions, and their corresponding relationships are analyzed.
