2. A concrete gravity dam has the following dimensions: Max water level = 305 m Bed level of river = 225 m, crest level = 309 m, D/S face slope starts at 300 m, D/S Slope= 2:3, C/L of drainage galleries at 8m d/s of u/s face, Uplift pressures: at Heal = 100 %, at Toe = 0 % at drainage gallery = 50 %. Assume density of concrete=2400kg/m3, no tail water, consider only self weight, hydrostatic and uplift pressure. Check the stability of dam for 1) rotation and overturning, 2) Translation and sliding, 3) overstress and material failure.
