A 10 m long 300mm diameter cfa concrete pile is to be used as a tension pile. The soil profile consists of 15m of firm clay overlying dense sand. Seasonally the ground water level varies between 1m and 2m below the ground surface. The undrained strength of the clay is equal to 80% of the effective vertical stress and its unit weight is 18kN/m^3 . Calculate the maximum tensile capacity of the pile.
