An excavation is to be performed in a stratum of clay, 9 m thick, underlain by a bed of sand. In a trial borehole, the ground-water is observed to rise up to an elevation 3 m below ground surface. Find the depth ofwhich the excavation can be safely carried out without the bottom becoming unstable under uplift pressureof ground-water. The specific gravity of clay particles is 2.70 and the void ratio is 0.70. If the excavation is tobe safely carried to a depth of 7 m, how much should the water table be lowered in the vicinity of the trench?

A 3 meter thick fill was placed over a 9 meter thick compressible clay. Underlying the clay layer is a very hard impermeable clay. The groundwater table is located on top of the compressible clay. A circular tank 9 meters in diameter transfers a surface contact stress of 45 kPa. Assume for this problem that the settlement of the fill and the very hard clay is small compared to the settlement of the compressible clay. a) Calculate the initial void ratio and saturated density of the compressible clay. b) Divide the compressible layer into two sublayers of equal thickness. The preconsolidation pressure is 100 kPa for the upper sublayer and 160 kPa for the lower sublayer. Calculate the following at the center of each sublayer: the increase in vertical stress caused by the tank underneath its center, and the consolidation setttlement due to the combined effect of the tank and weight of fill. c) How long will it take for 0.18 meters of settlement to occur? d) After 3.6 years, what…
A layer of sand 6 m thick lies beneath a clay stratum 5 m thick and above abed thick shale. In order to determine the permeability of sand, a well was driven to the top of the shale and water pumped out at a rate of 0.01m3/sec. Two observation wells driven through the clay at 15m and 30 m from the pumping well and water was found to rise to levels of 3m and 2.4 m below the ground water surface. Calculate the permeability of soil.
