Question A square footing is 1.8×1.8m with a 0.4×0.4m square column. it is loaded with an axial load of 1800KN and Mx =450KN.m, My=360KN.m. undrained triaxial tests(soil not saturated) give ∅=36° and C=20kpa. The footing depth D=1.8m; The soil unit weight gamma =18.00kn/m3; The water table at a depth of 6.1m from the ground surface. What is the allowable soil pressure if FS=3.0, using the Hansen bearing-capacity equation with B’,L’. Solution...
