Consider the following concrete retaining wall: 1.5ft La = 12° Sand: y = 115pcf 16ft d' = 32° c'=0 d' = (2/3) Concrete: y = 150pcf TAVI- N 3ft 5ft '1.5ft 6.5ft y = 120pcf ' = 22°C' = 200psf Clay Use Rankine active earth pressure with: cosa - Ka = cosa- cosa + cosa - cos2 cos2a - cos20 a. Calculate Rankine active and passive lateral forces and show their location onthe diagram. b. Calculate the factor of safety against overturning include active and passive forces). Present your calculations in a table format. c. Calculate maximum and minimum bearing pressures and sketch the pressure distribution at the bottom of the wall. d. Calculate factor of safety against sliding. Assume c, = (2/3)c' and 8' = (2/3) e. Calculate the Coulomb active lateral force and show its location (redraw the above sketch to avoid clutter). Make sure you calculate and clearly show the angle of the Coulomb force. Assume K Coulomb = 0.488.
