Parametric Numerical Study on the Impact of Internal Friction Angle and Pile Diameter on Soil deformation in Nasiriyah

الملخص

Clarifying the behavior of the soil near the bored pile foundation tips through   estimating the boundary of the influence has a great benefit theoretically and practically in the accurate design of pile foundations. This research presents an advanced geotechnical analysis of the piles in Nasiriyah soil applied to the foundation of the Al-Iskan Interchange project. The study employed finite element analysis, utilizing the Plaxis3d Foundation software to systematically investigate the impact of variations in internal friction angles and pile diameters on soil deformations. Through a parametric study, the research sheds light on the intricate relationship between these key parameters and the behavior of the soil. The findings reveal compelling insights: deformations exhibit a discernible pattern in response to internal friction angle and pile diameter alterations. Specifically, deformations demonstrate a diminishing trend with an increasing internal friction angle, while a contrasting escalation is observed with larger pile diameters. This nuanced understanding highlights the importance of selecting the depth to which the pile is driven. The depth refers to the soil with optimal values for internal friction angles and pile diameters in engineering projects, with direct implications for enhancing stability and minimizing deformation.
