2. Calculate the ultimate load carrying capacity of the pile tip driven into the soil profile shown below: G.W.T. Qapp 40' Soft Clay: Ysat 100 pcf Cu 500 psf, ₁ = 0° 4c+4 Poorly Graded Sand (SP): Ysat = 125 pcf Q₁ = ? c' = 0, ' = 35° Driven Steel Pipe Pile: Outside Diameter = 2' Inside Diameter = 1'11" Hollow (soil plugged) Note: Pile & soil profile are not drawn to scale For this problem, please calculate N₁* using both the bearing capacity theory approach and using standard design charts. Compare the values that result from these two approaches. Please use only the Nq* from bearing capacity theory for the remainder of your calculations.

Transcribed Image Text:2. Calculate the ultimate load carrying capacity of the pile tip driven into the soil profile shown
below:
G.W.T.
Qapp
40'
Soft Clay:
Ysat 100 pcf
Cu 500 psf, ₁ = 0°
4c+4
Poorly Graded Sand (SP):
Ysat = 125 pcf
Q₁ = ?
c' = 0, ' = 35°
Driven Steel Pipe Pile:
Outside Diameter = 2'
Inside Diameter = 1'11"
Hollow (soil plugged)
Note: Pile & soil profile
are not drawn to scale
For this problem, please calculate N₁* using both the bearing capacity theory approach and using
standard design charts. Compare the values that result from these two approaches. Please use
only the Nq* from bearing capacity theory for the remainder of your calculations.
