Abstract

© Copyright 2016 by the International Society of Offshore and Polar Engineers (ISOPE).In this study, effects of pile length and number of piles on settlement behaviour of pile groups are investigated. It is shown that the settlement of a pile group becomes independent from the number of piles beyond a certain point. Effect of pile length on settlement behaviour of the example foundation is also investigated. It is indicated that the settlement behaviour is becoming more effective in case the pile is longer. Besides, a relationship for group efficiency coefficient is suggested for estimating stiffness of a pile group using single pile stiffness by considering the interaction among piles and non-linear behaviour.
