Question $(2)$

You are tasked with the determination of the allowable load$-$bearing capacity $(Q_{\text{a}\text{l}\text{l}})$ of a concrete

pile, with a factor of safety of $3\mathrm{.}0,$ that is fully embedded in a saturated clay deposit.

Method to use:

The $-$method

Pile data:

Length $=20m$

Cross$-$sectional area $=381mm$ by $381mm$ square

Geotechnical investigation performed for this site yielded the following information:

Clay data:

Saturated unit weight $=18\mathrm{.}5k\frac{N}{m^3}$

Undrained shear strength $=70k\frac{N}{m^2}$

Groundwater location:

Below the pile tip
