You are in charge of designing piles for a site underlain by two layers. The top layer is an 10m thick layer of clay with OCR = 2, friction angle = 36 degrees, and Su = 50 kPa. The bottom layer is a 5m thick layer of sand with OCR = 1, and fiction angle = 38 degrees. Bedrock lies below the sand layer. In fact, assume that the UC test presented in the video (from problem 5 above) was conducted on a core extracted from your site. The nanoCT of that core showed no internal flaws (i.e., no weathering), and a value of X = 2 has been assigned to it (see page 60 of the reader). The structural engineer for the project has indicated that each pile must support a downwards load of 850 kN. You have selected to evaluate precast driven, square, high displacement piles with width B = 0.5m as possible alternatives: a. Alternative #1 (start on a new page; draw the profile with the pile): D = 8m. Find Qult St and Qult LT. Use Kulhawy's method to find the end bearing resistance. b. Alternative #2: (start on a new page; draw the profile with the pile): D = 15m (rests on rock). Find Qult. Use Ku wy's method to find the end bearing resistance.
