3. Consider a slope defined by H=100 ft, z=50 ft, yf= 60° and Yp = 40°. The tension crack is in the upper surface of the slop. The unit weight of the rock y=150 lb/ft and that of water Yw=62.5 lb/ft”. Assume that the shear strength of the surface is defined by Barton's equation with O=30°, JRC=6 and 0c=650,000 lb/ft2. Estimate the safety factor of the slope for two cases: 1) a drained slope in which Zw= 0; 2) a slope with a water filled tension crack defined by Zw = z. a =
