Question

The coefficient of earth pressure at rest is represented as _________ expression given by Jaky.

(a) K0=1-sinφ

(b) K0=sinφ

(c) K0=1-cosφ

(d) K0=cosφ

The question was posed to me in final exam.

I'd like to ask this question from Earth Pressure at Rest topic in portion Failure Envelopes & Earth Pressure of Geotechnical Engineering II

Answer 1

The correct answer is (a) K0=1-sinφ

For explanation I would say: The coefficient of earth pressure at rest is also computed from the expression given by Jaky in 1944 as,

K0=1-sinφ,

where, φ=angle of internal friction of the soil specimen.
