Studies on the corrrelation between the effect of confining pressure and the physical and mechanical properties of weak intercalations

We studied the correlation between confining pressure and the physical properties i>f fault gouge, and point out that confining pressure is the dominant in controling the void ratio and dry bulk density of fault gouge. There is a fine correlation between confining pressure and the void ratio and dry bulk density. Owing to the controlling effect of the confining pressure on the physical properties of fault gouge, the gouge gets a higher value of shear strength under the higher confining pressure. Here again a fine correlation exists between the confining pressure and the shear strength of the gouge. Les auteurs out étudié la correlation entre la pression confinante et les caractères de la fausse gouge, et montrent que la pression confinante et les facteurs determinants contrôlent le pore ratio et la densité de secheresse. Car le control la pression confinante sur les caractères physiques de la fausse gouge, lui faisant de trouver une haute valeur de l’intencité tranchante sous la pression confinante d&s; une valeur plus haute.
