From 3 to 6m the material is cohesive soil with C=10 kN/m$^{2}$, ɸ=10$^{\circ}$, $\gamma_{sat}=20 kN/m^{3}$. The water table is at 3m below ground level. And uniform surcharge of 10kN/m$^{2}$ acts on the top of soil. Draw the active earth pressure diagram detailing the values at the critical points. Also calculate the resultant thrust on the wall.
