Multiple choice

The undrained cohesion of a remoulded clay soil is 10 kN/m2. If the sensitivity of the clay is 20, the corresponding remoulded compressive strength is

  1. 5 kN/m2

  2. 10 kN/m2

  3. 20 kN/m2

  4. 200 kN/m2

C Correct answer
Explanation

Sensitivity is defined as the ratio of undisturbed compressive strength to remoulded compressive strength, or equivalently as the ratio of undisturbed cohesion to remoulded cohesion. Since sensitivity is 20 and undisturbed cohesion is 10 kN/m^2, the remoulded compressive strength is twice the remoulded cohesion, giving 20 kN/m^2.
