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 application of the axial load. The axial force is then applied very slowly. The equipment pore pressure lines remain open so that drainage of soil pore water can occur during the test. (The described conditions outline the procedure for a consolidated–drained-type test.) The sample fails (shears) when the σ3 pressure is 21 kPa and the s1 value is 61 kPa. From these data, determine the angle of internal friction for the effective stress strength–failure envelope (that is, determine fCD).

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.

8) A factory building is going to be constructed on a deep sand deposit. The project engineer has already taken samples from the site and applied laboratory tests (drained triaxial tests) to detemine the shear strength parameters of the sand. The unit weight of the sand is 16kN/m3. The void ratio of the sand is 0.5. Specific gravity is 2.65. In the test, the confining pressure is kept constant as 100kPa and the deviator stress increases gradually until 300kPa (at failure). Calculate the friction angle of the sand.
