Please Show all workings, the answer is b$)1224$kN c$)1783$kN:

Part b$)$

A shallow foundation, with width of $1\mathrm{.}5m$ and length of $2\mathrm{.}1m,$ is subjected to an

eccentric vertical load with an eccentricity of $0\mathrm{.}1m$ and $0\mathrm{.}15m$ in the width and length direction, respectively. The foundation is to be founded at a depth of $1\mathrm{.}2m$ in a layer of clay, which is subjected to variation in ground water level.

Using the guidelines provided in the Annex D of the Eurocode $7-$ Geotechnical Design

$($see Appendix $1),$ determine the ultimate bearing capacity of the foundation

immediately following the construction assuming that the water table is at a depth of $0\mathrm{.}3m$ below the ground level.

The soil properties for these conditions are: : ${}_{\text{d}\text{r}\text{y}}=17k\frac{N}{m^3},{}_{\text{s}\text{a}\text{t}}=20k\frac{N}{m^3},$ the

undrained shear strength $c_u=85k\frac{N}{m^2}.$

Part c$)$

Over a period of time the water level stabilizes at a depth of $0\mathrm{.}6m$ below the ground

level. Assuming drained soil conditions, determine the ultimate bearing capacity of the

foundation for this scenario.

The soil properties for these conditions are: $$ dry $=17k\frac{N}{m^3},{}_{\text{s}\text{a}\text{t}}=20k\frac{N}{m^3}$ and average

friction angle ${}^{\text{'}}=33.$
