Prediction of ultimate load bearing capacity of driven piles

Due to variation in soil layers, it is not easy for engineer to be assured that theoretical design of piles comply with the actual site condition. Thus, every design of piled foundations carries its own uncertainty and risk. This project evaluates the applicability of eight methods to predict the ul...
