Determination of load-transfer parameters of single piles axially loaded

摘要

Modern buildings require more use of the deep foundations including piles. The good perception of the behavior of piles and the knowledge of their bearing capacity is essential for a rational use. The present work focuses on the behavior of single pile under vertical loads in clay and sand soils. Thus, an approach to semi-empirical calculations load transfer as well as finite element modeling are used in order to determine the curve loading / sag at the head of pile and deduce the calculation parameters. This study has allowed predicting the load curves piles, knowing their geometric properties and some test results of in-situ soil (CPT, PMT and SPT).
