Figure 1 illustrates surcharge of 90 kPa was on the surface over an extensive area for a road construction project, where a 6m-thick layer of saturated clay (y= 20 kN/m³) is overlain by 4m of compacted soil (y= 18 kN/m³). The water table is at the top of the clay layer, and pore water pressures are hydrostatic below this depth. Calculate total stress, pore water pressure and effective stress, at the mid-depth of the clay layer; (a) Immediately after construction (b) After few years of completion. *Take the unit weight of water as 9.81kN/m³. 90 kPa Compacted soil 4m Clay 6m
