Eg.1 A strip footing of width $3\mathrm{m}$ is founded at a depth of $2\mathrm{m}$ below the ground surface in a $c??$ soil having a cohesion $\mathrm{c}=30\mathrm{kN}/{\mathrm{m}}^2$ and angle of shearing resistance $?=$ $35^{?}$. The water table is at a depth of $5\mathrm{m}$ below GL. The moist unit weight of soil above the WT is $17.25\mathrm{kN}/{\mathrm{m}}^3$. Determine (i) Ultimate bearing capacity (U.B.C) of the soil. (ii) the net UBC (iii) Net safe B.C. Use F $=3.0$ \& General Shear failure condition. If the water table occupies any of the positions: (a) $1.25\mathrm{m}$ below the base level of the foundation, what will be the net safe bearing capacity? (b) $1.25\mathrm{m}$ below the ground level. Assume saturated unit weight as $18.5\mathrm{kN}/{\mathrm{m}}^3$.
