Report Title:
Numerical Modeling of Drilled and Grouted Piles

 

Authors:
Rami Beylouni and Jean Louis Briaud, Texas A&M University

 

Report Date:
May, 1994

In this report two types of drilled and grouted piles, loaded with an upward force, are compared. For the first type, the upward load is applied at the top of the pile. For the second type, the load is applied at the bottom of the pile.

The study is performed in three steps. First, a finite difference analysis is performed using load transfer curves in order to obtain the load-movement curve for the piles. The second step is a finite element analysis where the stress distribution is observed along the pile-soil interface, and where the importance of the increase in radial stresses due to the compression of the pile is evaluated. Finally, a theoretical evaluation of the Poisson’s ratio effect is performed. The results show the advantages of loading drilled and grouted piles at the bottom.
