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)
