Laboratory Determination of Hydraulic Conductivity

Hydraulic conductivity is the measure of flowability of water inside the soil in the presence of a hydraulic gradient. The hydraulic gradient is defined as the difference in the water heads in the soil, which induces a water motion. In simple terms, a hydraulic gradient is the presence of a potential that induces a flow of water.

Question 15 A consolidated-undrained tri-axial test was conducted on a normally consolidated clay sample and the results are as follows: Chamber confining pressure = 109 kPa, Deviator stress at failure = 98 kPa, Pore Water Pressure = 53 kPa. These results were used to determine the drained friction angle of the soil. Compute the deviator stress (kPa) at failure when the drained test was conducted with the chamber confining pressure changed to 151 kPa. Round off to two decimal places.

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?
