Q$1$: It is proposed to construct a $12m15m$ raft at $2m$ depth within an over consolidated clay applies a riet pressure of $110k\frac{N}{m^2}$ to the underlying ground where $cu=45k\frac{N}{m^2},{}_s=17k\frac{N}{m^3}.$ The thick of clay layer was $8m,e_0=0,3,C_c=0,001$ and swelling index $=0\mathrm{.}004,$ Not that the pre consolidation pressure was $200$kPa. What would be$?$

a$.$ The net allowable bearing capacity of the rafi foundation

b$.$ The net allowable beaning capacity of the raft if a maximum consolidation settlement of $50mm$ is allowed? $[M25]$
