Advanced Geotechnical Engineering: Soil-Structure Interaction and Ground Improvement Techniques for Enhanced Foundation Performance in Challenging Soils

Abstract

Soil-structure interaction (SSI) significantly affects the performance and safety of foundations in challenging soil conditions. This paper reviews advanced geotechnical engineering methods focusing on SSI and ground improvement techniques. Using sophisticated numerical modeling approaches such as finite element method (FEM) and discrete element method (DEM), combined with innovative stabilization methods like deep soil mixing, jet grouting, and geosynthetics, foundation behavior can be optimized for reliability and cost effectiveness. The study highlights the integration of these techniques in foundation engineering and presents illustrative case studies demonstrating improved structural performance. Future directions toward sustainable and smart geotechnical practices are discussed.
