WebbIn principle, the effective stress principle can be applied to unsaturated soils (e.g., Bishop 1959; Blight 1961; Donald 1961). In reality, two practical difﬁculties hinder the direct application of the effective stress principle in unsaturated soils. First, the pore pressure is tensional and is not as easily measured or calculated as
