A deep foundation is planned to be designed for a rigid reinforced concrete structure. Supportration distance is equal to $10m$ and load transmitted to each support consists of an axial

load of $275t$ and bending moments of $12\mathrm{.}5t*m$ y $5t*m.$ Pile cap height will be $1m.$

The previous figure shows a scheme of the ground. The following parameterThe solution must contain at least the following sections:

$$ Type of pile $($driven o or drilling$)$

$$ Number of piles

$$ Diameter of piles

$$ Determination of the skin friction capacity in clays $($by any of the existing formulations$)$

$$ Determination of the skin friction capacity in sands $($by any of the existing formulations$)$

$$ Determination of the end bearing capacity in sands $($by any of the existing formulations$)$

$$ Determination of the maximum load withstood $($by any of the existing formulations$)$

$$ Determination of the vertical load transmitted $($by any of the existing formulations$)$

$$ Determination of settlements in piles $($by any of the existing formulations$)$s are known:
