7. Assume the water table drops 3 feet for the soil profile shown. What settlement will occur? Assume the unit weights above the water table for the initial condition will extend downward to the water table at its new position. 14' V Sand, y = 110 lb/ft3 Sand, Ysat 116 lb/ft³ e, = 0.9 N.C. C = 0.25 C, = 0.06 clay Ysat = 120 lb/ft³ sand

The stresses induced by a surface load on a loose horizontal sand (ɸ = 30o) layer were found to be σv = 6.0 kPa, τv = 1.6 kPa, σh = 3.7 kPa, and τh = -1.6 kPa. By means of Mohr circles, determine if such a state of stress is safe. If so, what is the factor of safety? Use FS = τff(available) / τf(applied) for the definition of factor of safety.

22. A sample of moist soil has a water content of 26%, a void ratio of 1.1, and a Gs of 2.7 a. Draw the phase diagram and fill it in with numerical values b. Determine S, n, yd, Ysat, Ysub

1. Develop the relationship a. G + Se y = Yw 1+e from a block diagram expressed in terms of G, e, S and y, b. What is the void ratio and buoyant unit weight of the soil if G, = 2.70 and Yoe = 1.5 y, (S = 1)?

The maximum and minimum unit weights of a granular soil are 117.1 lb/ft3 and 91.0 lb/ft3, respectively. Gs 5 2.65. What would be the relative density of the same sand compacted to a void ratio of 0.625?

4. Calculate the total settlement of two clay layers? The two clay samples at Location A and Location B were collected and analyzed. Use information at Location A to estimate the settlement at the stiffy silty clay. Use information at Location B to estimate the settlement at the very stiff clay. Compression index C, at point A is 0.25, C, at point B is 0.2. Swelling index C, at point A is 0.08, C, at point B is 0.06. Initial void ratio eo at point A is 0.66, eo at point B is 0.45. Maximium vertical stress cat point A is 101 kPa, at point B is 510 kPa. The 8.5 m thick proposed fill generated a increase of vertical stress = 20.3x8.5 = 172.55 kPa. 8.5 m 2.0 m 3 m 7.0m 4 m 4 mⒸ 4 m5 18.0m 5 mo 5 m Proposed Fill y=20.3 kN/m² y-18.3 kN/m² 7-19.0 kN/m² y-19.5 kN/m² 4.0 Stiff Silty Clay (CL) 10.0 Very Stiff Clay (CL) Glacial Till
