Axisymmetric Biot's Consolidation of Multi-Layered Soils with Compressible Constituents

Uncoupled state space solution to layered poroelastic medium with anisotropic permeability and compressible pore fluid

“…Some experimental results have shown that horizontal permeability of the soil may be an order of magnitude, or even more greater than vertical permeability. On the other hand, the fluid phase of saturated soils and rocks is usually in the form of liquid-gas mixture, in which the gas is regarded as minute bubbles occupying in the liquid when the degree of saturation is high (approximately more than 70%), thereby the fluid phase behaves as homogeneous compressible pore fluid [16][17][18][19][20][21][22][23][24][25][26][27]. These studies further pointed out that the compressibility of pore fluid evidently influences the consolidation process and pore pressure distribution.…”
