The depth of water in a lake is 4 m. The soil at the bottom of the lake consists of sandy clay. The water content of the soil was determined to be 25.0%. The specific gravity of the soil grains is 2.70. Determine the void ratio and the unit weight of the soil. What would be the total stress, effective stress, and pore water pressure at the 5 m depth into the bottom of the lake? 2.11

1) Points: 10 A lake with a water depth of 12 m is underlain by a soil with a total unit weight of 18.2 kN/m'. Compute the total vertical stress, a, and the effective vertical stress, d, at a point 8 m below the bottom of the lake. 2) Points: 20 Develop a plot of o, u, and o'vs. depth for the soil profile below.

A 5m wide and 10m long rectangular foundation is built on a site where the soil profile consists of 3m of gravel and 4m of clay overlying rigid impermeable rock as shown in Fiqure 8. The foundation carries a surcharge loading of q-65 kN/m2 Initially the water table is 1 m below the surface of the gravel. The water table rises to the surface of the gravel slowly over a period of time and the surface loading induces an increase...

QUESTION 3 A saturated, normally consolidated clay has a water content of 30, a liquid limit of 40, and a plastic limit of 20. The specific gravity of solids in the clay is 2.70. After demolition of an existing building, the effective vertical stress in the clay reduced to half of the prior stress. Most nearly, how much will the void ratio of this clay increase after unloading?

For the soil strata, draw diagrams indicating the total stress, pore pressure and effective stress profiles to the bottom of clay layer. Fine sand has a thickness of 6 m (FST) with saturated unit weight of 18 kN/m2. Clay has a thickness of 8 m with saturated unit weight of 14 kN/m3 The water table is located at depth of 0.7 of fine sand thickness below the ground surface (i.e. depth=0.7*FST). Fine sand will sustain capillarity (suction). Assume the same...

Two undisturbed clay samples were taken from the middle of the
overconsolidated and normally consolidated clay layers in the soil
profile shown. The water table is at the top of the
overconsolidated clay layer. Consolidation tests were carried out
on the two samples and the results are summarized in the table
below. Assume that the bulk, dry, and saturated unit weights of the
sand are 16 kN/m3, 16 kN/m3 and 19
kN/m3, respectively. The specific gravity of the clay
