A direct shear test was performed in a 6cm x 6cm shear box on a sample of dry, cohesionless soil. Under a normal load of 40kg, failure occurred when the shearing force reached 26.65kg. Plot the Mohr s strength envelope and determine the angle of shearing resistance of the soil. Determine graphically the magnitude and direction of the principal stress at failure. 4. Two triaxial tests were performed on samples of a moist soil in an undrained condition. The all-round cell pressure during these two tests were 2.5kg/cm 2 and the samples failed under deviator stresses of 4.85kg/cm 2 and 6.70kg/cm 2 respectively. Determine the apparent cohesion and the apparent angle of shearing resistance of the soil (i) Analytically (ii) Graphically Do you expect to obtain the same values of the shear parameters if the sample were tested in drained condition? Explain your answers with reasons. 5. Laboratory triaxial tests were performed on three soil samples of 3.8cm diameter and 7.6cm height. The following results were obtained; Sample no Cell pr.(kg/cm 2 ) Deviator load at failure (kg) Change in volume (cc) Axial Deformation(cm) 1 0.5 45 1.1 0.92 2 1.0 52 1.5 1.15 3 2.0 79.5 1.7 1.22 Plot Mohr s circles and determine the apparent values of shear parameters of the soil 6.

Group A 2. What are the different laboratory tests for determination of strength behavior of soil? Explain any one of the test. 3. A direct shear test was performed in a 6cm x 6cm shear box on a sample of dry, cohesionless soil. Under a normal load of 40kg, failure occurred when the shearing force reached 26.65kg. Plot the Mohr s strength envelope and determine the angle of shearing resistance of the soil. 4. Derive the expression for the shear strength of soil for vane shear test. Group B 5. As per geological classification, what are the different types of rocks? 6. Write in brief about slake durability test. 7. Write a short note on the different properties of the rock.
