CLO$1$: Identify, compute and analyse problems associated with retaining structures and sheet piles.

PLO$2$: Ability to critically identify, formulate, research literature, and analyse complex engineering problems based on first principles of engineering knowledge

Figure $1$ shows a retaining wall with the soil properties, $H=9m,H1=4m,y_1=16\mathrm{.}5k\frac{N}{m}3,Y_2=20\mathrm{.}2k\frac{N}{m^3}*\frac{O}{{?}_1{?}_1}=30,\frac{O}{{?}_2}=34,q=21k\frac{N}{m^2}.$
