Theory (Terzaghi-Meyerhof)
$$q_{ult} = c \cdot N_c \cdot s_c \cdot d_c + q \cdot N_q \cdot s_q \cdot d_q + \tfrac{1}{2}\gamma B' N_\gamma s_\gamma$$Bearing capacity factors: $N_q = e^{\pi\tan\phi}\tan^2(45+\phi/2)$, $N_c = (N_q-1)\cot\phi$, $N_\gamma = 2(N_q+1)\tan\phi$
Allowable: $q_{allow} = q_{ult}/FS$ Elastic settlement: $S_e = \dfrac{qB(1-\nu^2)}{E}I_f$
CAE Application: Initial design verification for FEM geotechnical analysis (PLAXIS, ABAQUS) / Comparison with pile foundations / Bearing capacity reduction after liquefaction / Slope proximity correction.
