Question
A 16 in diameter, 45 ft long drilled displacement pile is to be constructed in a silty sand with 30 percent fines, a mix of angular and rounded particles, and the following CPT profile:
Depth (ft) | 0–10 | 10–32 | 32–38 | 38–45 | 45–55 |
qc (tsf) | 25 | 50 | 61 | 78 | 200 |
The groundwater table is at a depth of 20 ft. Using NeSmith’s method and a factor of safety of 2.8, compute the ASD nominal downward load capacity, Pa.
