摘要: 再一次论述了地层面概念的合理性和公式p0=σ'+ppφ0。的正确性,并证明了公式p0=ppφ0+σ(1-φ)是错误的。指出了有效应力和颗粒压力是两个不同的概念,并指出了二者的差别。

Abstract: this paper discussed once more the reasonableness of concept of formation-surface and the correctness of formula p0=σ'+ppφ0. At the same time, it has been proved that the formula p0=ppφ0+σ(1-φ), is a erroneous one. The author suggested that the effective stress and granular pressure are two different concepts, and also pointed out the differences between them.

Key words: stress, formation pressure, balance, rock grain
