Problem for practice:

Situation $5.$

A $350$ mm $-$diameter and $12$ m $-$long concrete pile is driven

into the ground where the top $5$ m has $c_u=30$kPa;$=1\mathrm{.}0,$

which was underlain by clay with $c_u=100$kPa;$=0\mathrm{.}47$;$N_c$

$=9.$

Estimate the tip load capacity $(86\mathrm{.}6kN)$

Estimate the shaft load capacity $(527kN)$

Estimate the maximum load allowed safely on the pile

if the factor of safety is $2\mathrm{.}5(245kN)$
