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...
