Determine the allowable load capacity of the 0.4 m diameter pile shown in Figure 4. The fill is new and unconsolidated. A steel shell is proposed around the pile within the fill layer to eliminate the negative friction. The ground water level is at the middle of the fill layer. Use a factor of safety of 2.5. (y=moist unit weight: Ysat=saturated unit weight)
Steel shell Fill layer Ysat = 17 kN/m, y = 16 kN/m3 D'= 30° K=1.2 S=0.80' V. 4 m Clay (overconsolidated) Ysat = 19.5kN/m OR' = 30° 8'=0.60R' 10 m Sand Ysat = 18 kN/m?, y = 16.5 kN/m3 O'= 30° K=1.3 8'=0.86 18 m 0.5 m
