Ultimate Load Carrying Capacity of Pile Constructed in Sand

Ultimate load Qu = Qp + Qs - W

Where

Step One: Calculate Qp

Qp = Ab (Fb + Po)

Where

Ab = πr2

Ab = π x 2 = NaNm2

Fb = Nqσv

Where

σv = Zγ

Where

Fb = 18 x x = NaNKpa

Po = σv = x = NaNKpa

Qp = NaN (NaN + NaN) = NaNKN

Step Two: Calculate Qs

Qs = AsFs

Where

As = 2πrZ

As = 2 x π x x Z = NaNm 2

Fs = Nq/50σv'tanφ = Nq/50(σv/2)tanφ

Fs = 18/50 x NaN/2 x tan = NaN

Qs = NaN x NaN = NaNKN

Step Three: Calculate W

W = γcV

Where

V = πr2

V = π x 2 x = NaNm 3

W = x NaN = NaNKN

Finally, Ultimate Load Carrying Capacity, Qu

Qu = NaN + NaN - NaN

Qu = NaNKN
