Example No$\mathrm{.}3$: $,$ Sheet pile wall design $-$ cantilever wall

Design the depth of embedment of the wall, calculate load, tangential force and bending moment and draw distribution diagrams. Sheet pile wall supports surrounding soil $($sand$)$ and in the case b$)$ seals the pit of the same $H$ depth, too. Soil section consists of sand of thickness of $15$ m $.$ Soil data as ${}_{k^{\text{'}}},$ porosity $n$ and unit weight of solid particles ${}_S=26\mathrm{.}7kN{m}^{-3}$ are given $($characteristic values$).$

Ground water level:

a$)$ at $12$ m below origin ground level, the degree of soil saturation $S_r=0\mathrm{.}25,$

b$)$ at the ground level, dewatering by pumping in the foundation pit.
