1.
For the soil profile shown below, calculate and plot a profile of total vertical stress, pore
water pressure and effective vertical stress with depth. The position of the water table is
shown. Take into account water held in capillary action. Assume the height of capillary
rise is 5 feet and that the sand within the zone of capillary rise is 100% saturated.
Above the zone of capillary rise, the sand has a moist unit weight equal to the total unit
weight given of 112 lb/ft³.
