Authors: Gupta, Sunil Kumar
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.

Authors: Ghimire, Saurav
Abstract: Geosynthetic Reinforced Structures (GRS) play a pivotal role in various construction applications, serving as reinforced retaining structures, bridge abutments, and slope stabilizers. The technology employs geotextile or geogrids in backfill layers to develop tensile strength through friction and interlocking with the soil, minimizing settlement issues. GRS mechanisms involve apparent cohesion development, increased confining pressure, and potential soil dilatancy suppression. Research on GRS behavior encompasses factors like reinforcement spacing, stiffness, compaction effects, facing rigidity, and seismic behavior.
This study addresses a gap in understanding the impact of compaction load on lateral wall deformation during the serviceability stage. Utilizing Finite Element Method (FEM) 2D, the numerical model investigates compaction load effects on lateral wall deformation and reinforcement axial strain. Experimental findings underscore the influence of backfill compaction on soil stiffness and deformation reduction. Parametric analysis reveals compaction's substantial role in resisting lateral deformation, with decreased vertical reinforcement spacing and increased axial stiffness correlating with diminished lateral wall deformation. The study emphasizes that heavy compaction effectively mitigates both vertical and lateral deformation induced by traffic loads. Field modeling of a Geosynthetic Reinforced Bridge abutment validates these findings, showcasing the practical significance of compaction
