Webb1 feb. 2002 · Bishop's proposal was however not completely successful because of its geometrical interpretation of the coefficient χ appearing in the effective stress. This aspect is discussed briefly here and compared with a different interpretation of this coefficient examined on a number of soils by Khalili and Khabbaz (1998) and Khalili et al. (2001) … 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)
