Question
A closed ended precast concrete pile, circular cross section with 1 ft diameter, is driven in multi-layers
and is
shown in Figure. The pile is extended 2 ft above the finished ground level.
Please evaluate the single pile bearing capacity (Qult)
1. End Bearing (Op) by Meyerhof's Theory. (Hint: p.319, consider the critical limit)
2. Skin Resistance (Qs) (Hint: p. 320, consider the critical limit)
3. What is the ultimate bearing capacity (Qult) for this single concrete pile?
4. If the F.S. = 3.0, what is your design allowable bearing capacity (Qall) for this single pile?
2 ft
Silty Sand
Y = 105 Ib/ft3
Ø = 330
5 ft
Clay Sand
Y sat = 112.4 Ib/ft³
c = 200 lb/ft²
$ = 35°
20 ft
