Question

For μ=0.3, find K0.

(a) 0.429

(b) 0.289

(c) 0.536

(d) 0.375

This question was addressed to me in examination.

This interesting question is from Earth Pressure at Rest in chapter Failure Envelopes & Earth Pressure of Geotechnical Engineering II

Answer 1

Right option is (a) 0.429

The best I can explain: Given,

μ=0.3

\(K_0=\frac{μ}{1-μ}=\frac{0.3}{1-0.3} \)

K0=0.429.
