Question

A soil sample has a void ratio of 0.23. The specific gravity of the solids is 2.6. The saturated unit weight of the soil is most nearly

28 kN/m³

26 kN/m³

23 kN/m³

32 kN/m³

Answer 1

Given Voidratio (e) = 0.23 - Specitic gravity (G) = 2.6 We know that Formula derivation Saturated unit wt → Asat In = Gów (1+wsat) te From se. =w.G. Since saturated Degree of Saturati on+Sy=1 → res wsat: 47 Gów (it wsat) » Vsat = He = ów [G+G Wsat Ite ['es wat: G] = do Igte Ite Iesat = tw [gte] Ite vw= Unit wt of water G= Specific gravity of Soil es Void ratio s Scanned with CamScanner

e=0.23 G = 2.6 = 2.6 , Ves = 10 Kempen = 10 kn my Saturated unit wt dsat = col to CGte) lite = 10x (2-640-23) 1+0.23 Vsat = 23 kN/m² Saturated unit wt (osat) = 23 KN of Soil Ics Scanned with CamScanner
