N2  - Helical piles represent an efficient deep foundation system that has been widely used tosupport variety types of onshore and offshore structures. Predrilling process prior installation  alleviates the need for large torque to install high capacity helical piles. This research used  three dimensional Finite Element program (Plaxis 3D) to evaluate the performance of vertical single helical pile subjected to lateral loading. A comparison between the numerically  predicted response and four lateral load tests were conducted using full-scale helical piles is presented to assess the adequacy of the adopted numerical model. This study presents a  simulation for predrilling process of helical piles using two different approaches. The  parametric study involved helical piles installed in dry sand. The study aims to highlight the effect of different parameters on lateral capacity of helical piles. Furthermore, the strain wedge zone pattern mobilized around long and short helical piles were also investigated in addition comparisons were performed between the results of p-y curves method and results of the three dimensional finite element analysis for short helical piles
