Question 1 - Multiple Choice Questions (Mark: 18 X 3 = 54) Identify the choice that best completes the statement or answers the following questions. QUESTION 2 A retaining wall 6 m high supports a soil of saturated unit weight of 18 kN/m3 and φ =30°. The backfill is subjected to a surcharge of 20 kPa. 1. Calculate the total horizontal component of the lateral active force on the wall if the wall is rough (=18°). Groundwater is at the ground surface above the backfill soil....

Water content, w correct answers Ww/Ws (0 to 200%) Degree of Saturation, S correct answers Vw/Vv (0 to 100%) Unit Weight, gamma correct answers W/V (62.4 pcf or 9.81 kN/m3 for water) Mass Density, rho correct answers M/V = gamma/gravity (1000 kg/m3 for water) Total (wet) Unit Weight correct answers Wt/Vt = (Ws + Ww)/(Vs + Vv) = (1+w)*(dry unit weight) =Gs(1+w)(unit weight of water)/(1+e) Dry Unit Weight, gamma d correct answers Ws/V (60 to 125 pcf) Saturated Unit Weight, gamm...

unconfined aquifer correct answers The bottom flow boundary is defined by the aquiclude, but upper flow boundary (The groundwater table) is free to reach its own natural level. secondary consolidation correct answers Continuing settlement even after all pore pressures have dissipated Mohrs Circle correct answers Graphical representation of the relationship between normal stress and shear stress (transformation equations for plane stress) Quick Clay correct answers A water-saturated clay...
