A 600mm diameter pile is embedded in 3 layers of dense sand at a depth of 17m. Nq = 86. The groundwater table is situated between Layers 2 and 3. The layers have the following properties: Layer 1: γ = 16.9 kN/m3. 3m thick. Layer 2: γ = 17.6 kN/m3. 5.5m thick. Layer 3: γsat = 19.65 kN/m3. K is 0.9 and tan α = 0.37. The factor of safety is 3.0. What is the skin friction resistance of the pile in kN?

Question

A 600mm diameter pile is embedded in 3 layers of dense sand at a depth of 17m. Nq = 86. The groundwater table is situated between Layers 2 and 3.

 

The layers have the following properties:

  • Layer 1: γ = 16.9 kN/m3. 3m thick.
  • Layer 2: γ = 17.6 kN/m3. 5.5m thick. 
  • Layer 3: γsat = 19.65 kN/m3.

 

K is 0.9 and tan α = 0.37. The factor of safety is 3.0.

What is the skin friction resistance of the pile in kN?
