Behavior of piles and pile groups in cohesionless soils
Publication details: Washington DC : U.S. Department of Transportation. Federal Highway Administration. Turner-Fairbank Highway Research Center, 1985Description: 244 sSubject(s): Online resources: Abstract: In order to gain a better understanding of the behavior of piles in sand , an extensive search of the literature has been performed to collect data on instrumented piles driven in sand and tested under vertical loads . The load transfer characteristics of the piles were then analyzed without considering residual stresses. Wherever the data allowed it , the load transfer analysis was repeated after considering residual stresses. The results of this analysis were correlated with the available soil data to obtain a predictive method which considers residual 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.
