A drilled shaft of 5 ft in diameter and 60 ft in length is constructed on a site with the following soil profile. Xfrom (ft) Xto (ft) Type y (Rcf) Su (psf) N 60 0 15 CL 108 1200 ΝΑ 15 30 SP 120 ΝΑ 10 30 40 SW 130 ΝΑ 32 40 80 CL 132 3000 ΝΑ The ground water table is at a depth of 10 ft. The design follows AASHTO LRFD Bridge Design Specifications. (a) Sketch the pile and soil profile with the corresponding information labeled. (b) Considering the soil profile, which portions of the shaft should be ignored when estimating the side friction capacity? Indicate these portions in the sketch as well (c) Calculate the nominal side frictional capacity of each shaft segment. (d) Calculate the nominal toe bearing capacity of the drilled shaft. (e) Calculate the total nominal capacity of the drilled shaft (f) Is the pile a frictional pile, a toe-bearing pile or something else? (g) Choose a proper resistance factor for each resistance component (side friction on each segment and toe bearing), list your results (h) Calculate the total factored capacity of the drilled shaft |
