Three-Dimensional Analyses of Bored Pile and Barrette Load Tests Subjected to Vertical Loadings

Resumo

Full-scale load tests are usually conducted to obtain the reliable soil resistance at the site and to determine that the foundation is capable of sustaining working loads with sufficient safety. The aim of this study is to evaluate the interaction between test pile or barrette and the reaction system using the finite element code Plaxis 3D. The results show that the interaction between the test pile and reaction piles is more important than that between the test barrette and reaction barrettes. In addition, the results indicated that the interaction phenomenon depends on the pile slenderness and on the spacing between the test pile or barrette and the reaction system.
