1. Size footings for the following loads to equalize primary consolidation settlements. The maximum tolerable primary consolidation settlement is 2.5cm, while the maximum tolerable differential settlement is 0.64cm. Assume that the bearing capacity criteria will be met. You are to derive your compression indices from the strain vs. log effective stress curve given below. The sample for the consolidation test was obtained at the depth of 1.5m from the ground surface. The given curve is a laboratory curve and must be modified to a field curve and the settlement calculations can be expressed in familiar terms of void ratio with the given correlations.
The thickness of compressible clay is 30m. Settlement tabulation sheets have been attached for your convenience with the influence factors already set up for given depths using the Boussinesque`s theory. Solutions are iterative unless you guess right the first time.
The saturated unit weight of the soil is 1.85t/m3 and the initial void ratio is 1.20. The ground water table is located 0.6m below the ground surface.
