A concrete pile 15.24 m long having a cross section of 406 mm x 406 mm is fully embedded in a saturated clay layer for which Ysat = 19.02 kN/m³, = 0, and c, = 76.7 kN/m². Determine the allowable load that the pile can carry. (Let FS = 3.) Use the a method Eq. (12.61) and Table 12.11 to estimate the skin friction and Vesic's method for point load estimation.

Consider a 20 m long concrete pile with a cross-section of 0.407m x 0.407m fully embedded in sand. For the sand, given: unit weight, X = 18 kN/m³; and soil friction angle, += 35°. Using Meyerhof's method. Determine the ultimate point bearing Qp Consider a concrete pile in sand with a diameter equals to 0.407. The pile is 20 m long. Use K = 1.3 and '= 35, 8' = 0.8', X = 18 kN/m³. Compute the frictional resistance Q Consider the figure and the table below.
