Pore pressure coefficient B for saturated geomaterials with compressible, isotropic and uniform solid and fluid phases

This paper derives an expression for pore pressure coefficient $B in terms of a geomaterial’s mesoscopic properties and jacketed and unjacketed macroscopic compressibilities. The mesoscopic properties include phase compressibilities and pressure distribution ratios. The pressure distribution ratios represent the geomaterial’s meso-heterogeneity, while the difference between the unjacketed bulk compressibility and the solid grain...
