A tank foundation $12$ meter diameter is required to support an axial vertical load of $16400$ kN on the surface of a deep deposit of a stiff clay with Su $=82$ kpa, c$\text{'}=1\mathrm{.}2$ kpa, $=24$ degrees, Ysat $=20k\frac{n}{m^{3.}}$ Ground water table $isat$ the surface. $A90mm$ thick compacted base will $be$ placed $on$ the clay surface prior $to$ the construction $of$ the tank foundation. Calculate the short term bearing capacity, and $FS(Factorof$ safety. $)$
