Question

The value of pore pressure parameter, at failure for saturated clay is __________

(a) 1.2 to 2.5

(b) 2 to 3

(c) 0.3 to 0.7

(d) 0.7 to 1.3

The question was asked in class test.

Origin of the question is Shear Strength of Cohesive Soil topic in division Shear Strength of Geotechnical Engineering I

Answer 1

Correct answer is (b) 2 to 3

The explanation is: The approximate value of pore pressure parameter at failure for very loose, fine saturated sand, saturated clays is 2 to 3.
