Shaft Capacity Assessment of Recharge Impulse Technology Piles
The performance of Recharge Impulse Technology (RIT) in increasing the shaft capacity of deep foundation systems regarding classical set-processes is discussed. Based on the major contributors behind such a performance: the shape effect and the electrical discharge task, a case study is presented in view of highlighting that the coupling of these two components leads to a reasonable estimation of RIT shaft capacity with reference to in situ loading tests. A related design chart estimating the contribution of the shape effect in the increase of the shaft capacity had been drawn and a mean power law had been deduced through a parametric study on the adhesion factor.
Authors acknowledge Ahmed Amine Kammoun (Civil Engineer) for his contribution to the shape effect work. They equally express their gratitude to AfricSoil Tunisia, which had carried the in situ tests after RIT piles installation with a fair reasonable cost.
