BEHAVIOR OF PILES AND PILE GROUPS IN COHESIONLESS SOILS

Abstract

In order to gain a better understanding of the behavior of piles in snad, an extensive search of the literature has been performed to collect data on instrumental piles driven in sand and tested under vertical loads. The load transfer characteristics of the piles were then analyzed without considering reisual stresses. Wherever the data allowed it, the load transfer analysis was repeated after considering resiisual driving stresses. The results of this method as well as conventional and new in situ tests methods were then compared to actual load test results. Areas of critical need for further research are pointed out and recommendations are made for their implementation. (Author) (Author)
