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) Webbthe effective stress converts the analysis of a multiphase porous medium into a mechanically equivalent, single-phase, single-stress state continuum comprehension. In a similar manner to Khalili et al. [4], Figure 1 gives a schematic representation of the effective stress principle. The unified effective stress ij
