A soil profile consists of 12 m of gravel overlying a clay layer of 3.5 m thickness,which in turn rests on a 4 m sand layer. The dry and saturated unit weights of thegravel are 17.5 kN/m3 and 20.5 kN/m3. Unit weights of the clay and the sand are20 kN/m3 and 19.5 kN/m3 respectively. Below the sand layer lies impermeablebedrock. If a wide excavation of 3 m depth is to be made in a relatively short time,draw the effective, total and pore pressure diagrams before and a long time afterthe excavation is made. Ground water table is 5 m below the ground surface.
