Equations for Stress Relations in Porous Medium-in reply to Mr. Zhou Da-chen

Abstract

Abstract: 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.

Key words: porous medium, matrix stress, overburden pressure, pore pressure, equation
