8. An exploratory drill hole was made in a saturated stiff clay having a water content of 32%. It was observed that the sand layer underlying the clay was under artesian pressure water in the drill hole rose to a height of 4 m. above the top of the sand layer. If an open excavation is to be made in the clay. (See picture below) Determine the void ratio of clay. (Answer: 0.864) Determine the saturated unit weight of clay. (Answer: 18.76 kN/m3) How deep can the excavation proceed before the bottom of the saturated clay heaves or when its effective stress is zero. (Answer: 5.91 m)
A 3 m thick saturated soil stratum has a compression index of 0.25 and coefficient of permeability 3.2 x 10-3 mm/sec. If the voids ratio is 1.5 at vertical stress of 0.10 N/mm2, compute the voids ratio when the vertical stress is increased to 0.25 N/mm2. Also calculate settlement due to above stress increase and time required for 50% consolidation. Assume single drainage

Water in the drill hole rose to a height of 12 ft above the top of the sand layer. If an open excavation is to be made in the clay, how deep can the excavation proceed before the bottom heaves?
A clay layer of 30 m thick with a unit weight of 20 kN/m3 overlies a sand layer. The groundwater table is at the ground surface initially. A 20 m deep excavation is made in the clay layer. Piezometric measurements show artesian pressure at the bottom of the clay layer, amounting to a water level of 8 m above the excavation base. Calculate the factor of safety against the bottom heave for the excavation.
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?
