A soil layer consists of 4 meters of sand underlying 5 meters of clay. The water table is naturally located at the rock bed under the soil strata but rose by 6 meters due to a recent storm. Further, capillary action is expected to develop due to the nature of the soil in question. Compute the effective stresses at the end of expected capillary action, at the end of the water table, at the interface of the clay and sand and finally at the bottom of the soil strata. Pertinent soil properties are as follows:
4.5 meters of clay underlain by 4.5 meters of sand. Water table is 3 meters from the ground level. Capillary action is expected to occur. Calculate the effective stresses at the end of the capillary zone, at the end of the water table, at the clay-sand interface and at the bottom of the soil layer. Pertinent soil properties follow: Clay: e = 1.01. Gs = 2.721, Average saturation at the capillary zone = 50%, C = 30 mm2 and D10 = 1/75 mmSand: water content of 32.4723%Void ratio: Assume logical 4 significant figure value.
