For the soil strata, draw diagrams indicating the total stress, pore pressure and effective stress profiles to the bottom of clay layer. Fine sand has a thickness of 6 m (FST) with saturated unit weight of 18 kN/m2. Clay has a thickness of 8 m with saturated unit weight of 14 kN/m3 The water table is located at depth of 0.7 of fine sand thickness below the ground surface (i.e. depth=0.7*FST). Fine sand will sustain capillarity (suction). Assume the same...
