Strip footing, B=2m, Df=1.5m, c=20 kPa, φ=25°, γ=18 kN/m³. Find ultimate bearing capacity (Terzaghi).
For saturated clays under undrained conditions (φ=0), τ = c = undrained shear strength ( S_u ). The unconfined compression test gives ( q_u = 2c ). besavilla ce reference
[ Q = \frac{1}{n} A R^{2/3} S^{1/2} ] For trapezoidal channels, optimal depth ( d = B/2 ) for most efficient section (when side slope z=0). Strip footing, B=2m, Df=1
