Geotechnical Engineering Basic
Definitions
Dry unit weight of soil sample - correct answer γd = Ws/Vt =
Ws/(Vs+Vv)
Water content - correct answer ω = (Ww/Ws) x 100%
Weight of water in soil - correct answer Ww = Wt - Ws
Void ratio - correct answer e = Vv/Vs
Absolute Specific Gravity - correct answer Gs = γs / γ0 =
Ws/(Vs γ0)
Total volume of soil sample - correct answer Vt = Vs + Vv
Porosity - correct answer n = (Vv/Vt) x 100%
Percent Saturation - correct answer S = (Vw/Vv) x 100%
Volume of water - correct answer Vw = Ww/(Gw*γ0)
% solids - correct answer ns = (Vs/Vt) x 100%
% water-filled voids - correct answer nw = (Vw/Vt) x 100%
% gas-filled voids - correct answer ng = (Vg/Vt) x 100%
