A vane shear test was performed on saturated clay layer at the site and it is noted that a torque of 45 N-m was required to shear the soil. In order to remould the soil, the vane was rotated rapidly under the certain value of torque say “x”. If the sensitivity of the clay is 8, then calculate the value of “x” in N-m.
Assume diameter and length of the vane to be 70 mm and 130 mm respectively, consider two way shearing.
    Correct answer is between '5.5,5.7'. Can you explain this answer?

    Concept:
    Undrained shear strength of clay is given by:
    Where,
    S =shear strength of soil
    H = Length or Height of the vane
    D = diameter of the vane
    T = Torque applied
    Calculation:
    At undisturbed state:
    T = 45 N-m
    H = 130 mm = 0.13 m
    D = 70 mm = 0.07 m
    c = 38.129 kN/m2
    At remoulding state:
    Sensitivity of clay soil:
    cr = 4.767 kN/m2
    Now,
    Tr = 5.625 N-m (Ans).

    15 N-m. Once the soil was remoulded, a second vane shear test was performed and it was found that a torque of 30 N-m was required to shear the soil. This indicates that the soil had lost some of its shear strength due to remoulding. It is important to note that remoulding of soil can significantly alter its properties and therefore it is important to carefully consider the effects of any disturbance on soil before making any design decisions.
