Question
Two identical concrete piles having the plan dimensions are driven into a homogeneous sandy layer as shown in the figures. Consider the bearing capacity factor for as 24.
If and represent the ultimate point bearing resistances of the piles under dry and submerged conditions, respectively, which one of the following statements is correct?
Correct answer
(A) Qₚ₁ Qₚ₂ by about 100%
Solution
The ultimate point bearing resistance of a pile in sand is given by .For Case 1 (Dry Sand):
Effective vertical stress at the tip, .
.For Case 2 (Saturated Sand):
Effective vertical stress at the tip, .
.Comparison:
Ratio .
This means is approximately twice , or is greater than by about 100%.Thus, option (A) is correct.
Effective vertical stress at the tip, .
.For Case 2 (Saturated Sand):

.Comparison:
Ratio .
This means is approximately twice , or is greater than by about 100%.Thus, option (A) is correct.
