axially loaded pile of radius ro=0.5mand length =40mis made of concrete with Young's modulus Ep=25GPa. It is driven through soil with shaft shear transfer stiffness =4MPaand ends with its toe in firmer ground with base transfer stiffness b=100/MPa. The base of the pile is under-reamed to a radius of rb=1m. What is the axial stiffness of the pile Pt/t, and what proportion of the load reaches the toe of the
