- Answer any one asap 1.A triaxial test is performed on a normally consolidated clay. The sample is further consolidated by the test of all-around confining pressure prior to the application of the axial load. The axial force is applied very slowly. The equipment pore pressure lines remain open so that drainage of the soil pore water can occur during the test. The sample fails when minor principal stress is 49 kPa and the major principal stress is 91 kPa. Determine the angle of internal friction with no decimal places. 2.A dry sand sample was tested in direct shear and yielded a shear strength of 132 kPa under a normal stress of 215 kPa. Lab results indicate the soil's wet unit weight is 18.1 kN/m3 and the saturated unit weight is 20.2 kN/m3. Determine the shear strength, in kPa, within the native sand deposit at a depth of 2.5 m below the water table. The water table is 3 m below ground surface.
