"Design" (i.e., check against sliding, overturning and location of the resultant force for) a 15-foot-high concrete cantilever retaining wall with a vertical back face in a horizontal sandy soil (y=115 pcf and (N₁)60.avg=26). The retaining wall shall be designed to support a traffic load that can be represented by an equivalent surcharge load of q = 600 psf. a) First, design the wall using the following dimensions: b= 12 inches, B = 6 feet, D = 1.5 feet, Tstem = Tfooting Soffset= 1.5 feet. Check to see if the retaining wall has adequate factors of safety against overturning and sliding (assume μ = 0.6) and whether the footing will lift off. Draw the bearing pressure diagram. b) If the dimensions in part (a) are not adequate to provide stability against overturning, sliding, and liftoff, develop a spreadsheet and use it to "design" the wall (i.e. provide values of b, B, D, Soffsets Tstem, and Tooting). (Hint: the dimensions in part (a) are not adequate).
