asked Feb 8, 2022 in Geotechnical Engineering I by Sophia (102k points)

The quick condition takes place when effective pressure is _______

(a) σ’=0

(b) σ’=1

(c) σ’= zγ’+ ps

(d) σ’= zγ’

I got this question by my college director while I was bunking the class.

The origin of the question is Seepage Pressure and Upward Flow in division Seepage Analysis of Geotechnical Engineering I

geotechnical engineering i
seepage analysis

Best answer

The correct choice is (a) σ’=0

The explanation: When seepage pressure equals the pressure due to submerged unit weight γ’, quick condition takes place.

∴ σ’= zγ’- ps

∴ σ’=0.
