WebbEffective stress σ0 is the stress acting on a soil’s skeleton due to the total stress σ, pore water pressure (Terzaghi 1943), interparticle capillary stress (Bishop 1959), and adsorptive stress (Lu and Likos 2006). A general effective stress is proposed (Lu and Likos 2006), using the suction stress σs as a function of water content w, includ- WebbSummary: the article describes the principle of effective stress as it relates to the historical events that led to its development.

Effective Stress Principle for Partially Saturated Rock Fractures

WebbWe know total stress at any point within a soil mass can be written as this: total stress (σ) = effective stress (σ’) + pore water pressure (u) σ = σ' + u. from this we can write expression for effective stress: σ’ = σ – u. This relationship was proposed by … WebbThe principle of effective stress is looked at and a brief historical account which promoted its development is given.

Webb1 mars 2024 · The general structure of the effective stress is known using Eq. (9), which depends on the thermodynamic pressure given by Eq. (55) P T = P 0 + ∑ α ϕ α Δ u α = u A + ∑ ϕ α ( u α − u A). By rearranging the last equation we can always (formerly) express PT in a Bishop form with χ = ϕ W + ϕ S ( u A − u S) / ( u A − u W).

The proposed model shares the same form with Bishop’s … WebbA definition of effective stress in partly saturated soils has been proposed by Bishop (1959) (see also Bishop, Alpan, Blight and Donald, 1960). σ' = σ - u a + χ (u a - u w) (3.8) where χ is a parameter which may vary from 0 to 1. When χ = 1 the soil is saturated and equation (3.8) simplifies to σ' = σ - u w (3.6)
