Question

Khosla’s theory can be used for calculating which of the following?

(a) Uplift pressure and exit gradient

(b) Seepage pressure

(c) None of the mentioned

(d) All of the mentioned

I had been asked this question during a job interview.

My question comes from Seepage Analysis in division Seepage Analysis of Geotechnical Engineering I

Answer 1

Correct choice is (a) Uplift pressure and exit gradient

For explanation: Khosla’s theory has an account of flow pattern below the impermeable base of hydraulic structures, hence it can be used to calculate the uplift pressure and the gradient at the exit, called the exit gradient.
