Use the lambda method to calculate the axial capacity of a long steel pipe pile installed for an offshore project. The pile has a 0.45 m outside diameter and penetrates 60 m into normally consolidated clay. Soil conditions are as follows: From zero to 15 m depth, the soil cohesion is 45 kPa and the saturated unit weight is 16.5 kN/m³; between depths of 15 m and 35 m, the soil cohesion is 65 kPa and the saturated unit weight is 18 kN/m³; below 35 m, the soil cohesion is 110 kPa and the saturated unit weight is 19 kN/m³. The water surface is above the soil surface. Apply a factor of safety of 2.
