A concrete pile of size 0.4 x 0.4 m is driven to a depth of 12 m into medium dense sand. The water table is close to the ground surface. Static cone penetration tests were carried out at this site by using an electric cone penetrometer. The values of qc and fc as obtained from the test have been plotted against depth and shown in Fig. Ex. 15.20. Determine the safe load on this pile with F_{s}=2.5 by Schmertmann’s method (Section 15.21).
