A 2-foot thick concrete (y-145 pcf) retaining wall is planned to be constructed as in the figure at right. The coefficient of base friction for the wall is 0.43. Question #1 (6 pts.): Determine the active earth pressure against the retaining wall, and check the wall for factors of safety against sliding and overturning. Question #2 (4 pts.): Create the base pressure profile of the retaining wall, and determine, on its basis, the minimum safe bearing pressure of the soil. 15 ft 2 ft 8 ft 4 ft 3 Sand c' = 0 ' = 33 deg. y = 126 pcf A 2-foot thick concrete (y-145 pcf) retaining wall is planned to be constructed as in the figure at right.
