please answer the eqestions and show all the steps 7-18 A field Vane shear test was conducted in a deposit of soft clay. The Vane was 10 mm long and 50 mm in diameter. A maximum torque of 19.3 Nm...
Q3. Vane shear tests were conducted in layer of soft clay. The vane dimensions were 63.5 mm (D)x 127 mm (H). At a certain depth, the torque required to cause a failure was 0.051 kN.m. The liquid limit of the clay was 56 and the plastic limit was 23. Estimate the undrained cohesion, c of the clay for use in the design by applying Bjerrum's λ relationship given below. Investigate about what is Bjerrum's relationship: 1.7-0.54 log[PI(%)] Discuss when you...
