Question

The consolidation settlement ρf for a soil stature of thickness H that has fully consolidated index, a pressure increment ∆σ’ with respect to mv is given by ____________

(a) ρf=mv H

(b) ρf=H∆σ’

(c) ρf=mv H∆σ’

(d) ρf=mv ∆σ’

The question was asked in an online interview.

I'd like to ask this question from Consolidation Process in portion One Dimensional Consolidation of Geotechnical Engineering I

Answer 1

Right option is (c) ρf=mv H∆σ’

To explain: Since the change in thickness is given by,

∆H= -mvHo∆σ’,

The consolidation settlement ρf for a soil stature of thickness H that has fully consolidated index, a pressure increment ∆σ’ with respect to mv is given by,

ρf=mv H∆σ’.
