摘要
提出了基于多孔介质的一种新的有效应力原理．据此，当饱和土加载后，孔隙度的变化与孔隙水压力之间的关系是非线性的，它们之间的变化关系同样取决于初始孔隙度以及初始孔隙水压力．
A new principle of effective stress based on porous medium is given in this paper. It is indicated that the relationship between excess porewater pressure and the porosity is nonlinear when there is a load on the saturated soil. The relationship also depends on the initial state of the porous media and the initial pore-water pressure.
