Determine the safe load that can be carried by a RCC pile having a gross weight of 1.5t using Modified Hiley's formulae from the following data: a. Weight of drop hammer = 2t, Height of free fall = 91cm, Hammer efficiency =75% b. Average penetration under last five blows=10mm, Length of pile = 22m, Dia. of pile=300mm, c. A well - conditioned driving cap and helmet with hard wood dolly is used for driving. d. Assume factor of safety as 2.5. (Ans:17.7 t)
