Granular upper layer

$q_{\text{u}\text{l}\text{t}}=p_0*N_q^{**}*s_q^{**}+\frac{1}{2}**B*N_{}^{**}*s_{}^{**}$

$2,5$ meters wide by $3$ meters long footing

Since it is a granular layer, it is assumed that cohesion is $0(c=0$kPa $)$ and friction angle is ${35}^a$

The soil's specific weight $=19\mathrm{.}0k\frac{N}{m}3.$

The footing is embedded at $1\mathrm{.}2m$ below natural soil

The distance from the support level to the rigid layer is $2\mathrm{.}5m.$

No water
