Numerical Analysis of Load Settlement Behavior in Sand Deposits for Axially Loaded Pile

Abstract

This study presents a comprehensive numerical analysis of the load settlement behavior in sand deposits surrounding axially loaded piles, aiming to enhance the understanding of pile-soil interaction in geotechnical engineering. The research employs advanced finite element modeling techniques to simulate the intricate mechanical response of piles subjected to axial loads within sand deposit. The numerical simulations incorporate crucial parameters such as soil-pile interface characteristics, and loading conditions to investigate their impact on the load settlement behavior. The study reveals insights into the mobilization of skin friction and end-bearing resistance within the sand matrix, shedding light on the complex mechanisms governing pile performance in different geological contexts The findings of this numerical analysis contribute to the advancement of geotechnical engineering practices, offering a deeper understanding of the factors influencing the load settlement behavior of axially loaded piles in sand deposits. A load-settlement curve was generated, extrapolated, and simulated using Plaxis 3D using various stiffness correlation with SPT value. Papadopoulos (1982) established a correlation that shows a close prediction about 2.1% more with field settlement values. Bowles and Tromienkov's correlations underestimate settlement values by 16 %, while Chaplin and Webb's correlations overestimate settlement by 34% and 29% respectively.
