The 'sensitivity' of a soft clay is expressed as:
Choose the correct answer
Ratio of compression index to swelling index
Ratio of undisturbed Su to remoulded Su — higher sensitivity = more strength loss on disturbance
Temperature sensitivity of clay
Chemical sensitivity to pH changes
Correct Answer
B. Ratio of undisturbed Su to remoulded Su — higher sensitivity = more strength loss on disturbance

Sensitivity St = undisturbed Su / remoulded Su (both at same void ratio). St < 2: insensitive; 2–4: slightly sensitive; 4–8: sensitive; 8–16: very sensitive; > 16: extra-sensitive; > 100: quick clay (Scandinavian clays with leached salt — lose all strength on disturbance). Quick clays are dangerous in landslides. Indian marine clays: St = 4–8 typically.
