摘　　要：上覆岩层压力与下伏岩层中的流体压力以及岩石骨架应力之间,存在着一定的关系。这三者之间到底是什么关系,应该如何进行表述和刻画,出现了不同的认识。这涉及到对多孔介质力学的有效应力这一基本概念的认识和理解,是很重要的问题。基于对多孔介质双重有效应力的研究,重申了多孔介质中任一点处,上述三种应力之间的正确关系,并把相应的数学表达称为多孔介质的应力关系方程。There are certain relations among overburden pressure,underlying fluid pressure and matrix stress,and different understandings of how to describe or depict them in the end.This is an important question involving how to understand the basic concept of effective stress in porous medium mechanics.This study restated proper relations among these three stresses at any locations in porous medium,and called the corresponding mathematical expressions the stress-based equations of porous medium.

关 键 词：多孔介质 骨架应力 上覆岩层压力 孔隙压力 岩石力学
