Homework $1$

A rectangular footing $(4m^{**}2m)$ in plan. the soil supporting the foundation has a friction angle $\frac{O}{?}=30$ and $C=25k\frac{m}{m^2}.$ The until weight of soil, $=17\mathrm{.}5K\frac{N}{m^{3.}},$ Determine the allowable bearing capacity of the soil.

Assume that depth of foundation $(D_f)$ is $=3\mathrm{.}0m$ and $F.s=3.$ And the water table at $1\mathrm{.}0m$ from the surface ground
