As shown in figure 1.0, a 0.8 m diameter round steel pile driven into a sandy soil stratum. Assume that the critical depth is achieved at 20 d. Compute the allowable pile capacity with FOS 3.0. Further, assume the mid-depth concept for effective stress calculations to compute the total skin frictional capacity of the pile. 10 m -30, y 18 kN/m, K-1.25 Sand Layer-1 20 m 2 m -30, y 18 kN/m, K-1.25 V Sand Layer 2 0-32, y-32 kN/m, K-1.25
