  1. A triaxial test was performed on a dry, cohesionless soil under a confining pressure (?3) of 144 kN/m2. If the sample failed when the deviator stress (∆?) reached 395.8 kN/m2, determine the soil’s angle of internal friction ∅ and the angle of the failure plane θ.

Please make your numbers legible, thank you

A sample of normally consolidated clay was subjected to a CU triaxial compression test that was carried out until the specimen failed at a deviator stress of 50 kN/m2. The pore water pressure at failure was recorded to be 18 kN/m2, and a confining pressure of 48 kN/m2 was used in the test. The cohesion of the clay was 20 kN/m2 at the failure. draw both the effective stress strength envelope and total stress strength envelope. identify the effective internal...

A drained triaxial test is conducted on a soil with friction angle of 25° and zero cohesion, using a chamber pressure sc=300 kPa and a back pressure (this is the term used to denote the initial value of the pore pressure, u0) equal to 200 kPa. The shear stage of the test is performed DRAINED by increasing the axial stress s1, while concurrently decreasing the chamber pressure s3 so that their sum remains constant (s1+s3 = constant). Draw the effective...

During a consolidation test, a sample of fully saturated clay 3 cm thick is consolidated under a pressure increment of 200 kN/m2 . When equilibrium is reached, the sample thickness is reduced to 2.60 cm. The pressure is then removed and the sample is allowed to expand and absorb water. The final thickness is observed as 2.8 cm and the final moisture content is determined as 24.9%. If the specific gravity of the soil solids is 2.70, find the void...
