The effective stress acting on the soil matrix in a saturated soil is the difference between the total stress and the water pressure. This principle called the stress principle of Terzaghi has been used also by Biot and is accepted for saturated soil. For unsaturated soil more sophisticated formula has been used.
Poroelasticity is a field in materials science and mechanics that studies the interaction between fluid flow and solids deformation within a linear porous medium and it is an extension of elasticity and porous medium flow (diffusion equation). The deformation of the medium influences the flow of the fluid and vice versa. The theory was proposed by Maurice Anthony Biot (1935, 1941) as a theoretical extension of soil consolidation models developed to calculate the settlement of struct…
WebIn Biot's theory (Biot 1956a, b), pore fluids are forced to participate in the solid's motion due to inertia and viscosity. The Biot mechanism is described through macroscopic rock … Web2. The full three dimensional approach based on the Biot theory. In most of the studies done on the Bangkok region, the one dimensional theory of Terzaghi has been chosen. This is mainly because of the simplicity of the computation. In this section, we analyze the validity of the assumptions of the consolidation theory of Terzaghi.
