A 20 m long concrete pile with a rectangular cross section of 460 mm x 460 mm fully embedded in sand is shown in Figure P 12.2. Estimate the ultimate point load or tip resistance Q, by each of the following 4 methods and discuss. Necessary variables and formulae: Area of the pile tip Ap q' Pa ō'o Irr Ir A Hs Effective vertical stress at the level of the pile tip Atmospheric pressure 100 kN/m² Mean effective normal ground stress at the level of the pile point Reduced rigidity index for the soil Rigidity index for the soil Average volumetric strain in the plastic zone below the pile point Poisson's ratio of soil 1) Terzaghi's method (Use Na = exp[(37-0') tan o'] 1-sin o'
