Problem 3) Shown below is a cross-section through a soil layer. A Shelby tube sample was taken from a depth of 25 ft. The sample was extruded in a laboratory, thus subjected to zero total stress. Assume Ko = 0.5 and Ā = -0.1, determine the effective stress on the sample after extrusion. Use the basic Skempton (1954) and Ladd and Lambe (1963) approach to determine the change in pore pressure.

An oil-water SS displacement experiment was carried out on a 5.0 cm long and 3.0 cm diameter sandstone core plug taken from Duyung-1 well in Terengganu. The porosity of the plug is 25% and the grain density is 2.65 g/cm3. Oil and water densities are 0.85 g/cm3 and 1.05 g/cm3, while viscosities are 2.0 cP and 1.0 cP, respectively.

In an oedometer test on a saturated specimen (G,- 2.70, the initial thickness Ho-2.0cm), when the applied pressure increased from 100 to 200 kN/m², after 1440min the thickness of the specimen changed from 1.99cm to1.97cm. After the test, the specimen was removed and the thickness changed to 1.980cm, and the moisture content was determined to be w=27.8%.

A clay sample was consolidated in a triaxial cell under a backpressure of 50 kPa and cell pressure of 150 kPa. The drainage valve was then closed and the cell pressure was increased to 200 kPa when the pore pressure increased to 98 kPa. What is Skempton’s B-parameter? The above sample was then subjected to a vertical deviator stress, which was increased from zero under undrained conditions. The sample failed when the pore water pressure was 160 kPa and the deviator stress was 70 kPa. What is Skempton’s A-parameter at failure? Assuming the clay is normally consolidated, find the friction angle in terms of effective stresses.
A fully saturated cylindrical triaxial sample of clay soil has approximate initial dimensions of 38mm in diameter by 76mm long. A quick undrained triaxial test is conducted on the specimen where the cell pressure is 140 kN/m2. In this the deviator stress at failure is 76 kN/m2. After the triaxial test, a water content test is conducted on the entire sample. The combined weight of the wet sample and sample container was 181.7 g. The combined weight of the oven dried sample and sample container was 147.8 g. The sample container weighs 9.2 g. The soil solids specific gravity is 2.7. What is the undrained strength of the soil? Also, what are the water content of the soil, its total (or bulk) unit weight, and its voids ratio?
