WebbAs the water pressure is added, the slope of the active pressure diagram (K a γ’ + γ w) is more than that above the water table (solid line). The total or resultant active earth pressure exerted on the wall is obtained by computing the area of the pressure diagram. WebbLet’s begin with the soil surface. Total stress on the surface of the soil is because of the surcharge only. So total stress is equal to the surcharge q. σ = q . No water present above this plane, hence pore water pressure is zero. u = 0 . So effective stress which is total stress minus pore water pressure is q. σ’ = σ – u. σ’ = q ...
