Geotechnical Design Exam I || with 100% Correct Answers.

Moisture Content correct answers w = Ww/Ws Unit Weight correct answers Gamma = W/V = (Ws+Ww)/V Saturated Unit Weight correct answers Gamma_sat = Wsat/V = (Ws+Ww-sat)/V Dry Unit Weight correct answers Gamma_d = Ws/V Void Ratio correct answers e = Vv/Vs Degree of Saturation correct answers S = Vw/Vv * 100% Liquid Limit (LL) Plastic Limit (PL) Shrinkage Limit (LL) (Atterberg Limits) correct answers (Solid State) |SL| Semi-Solid State |PL| Plastic State |LL| Liquid State. --- w (%) (moisture content) Relative Density (D_r) (associated with sandy (coarse grain (gravel, sand) soils) correct answers D_r(%) = (e_max-e)/(e_max-e_min) * 100 STRESSES IN SOIL correct answers In-situ Stress (initial stress before constructing foundation). Induced Stress (induced by foundation) Effective Stress Concept correct answers effective stress (particle to particle contact stress) = sigma' = sigma - u sigma = gamma*h = total stress u = gamma_w*h = pore water pressure Consolidation Settlement correct answers S_c = Consolidation Settlement (primary consolidation settlement) Sigma'_z0 = Initial effective stress ∆sigma'_z = incremental effective stress e_0 = initial void ratio ∆e = change in void ratio due to consolidation (caused by ∆sigma'_z) H_c = thickness of the consolidating layer
