Abstract: Soil stabilization plays a crucial role in enhancing the structural integrity of foundations, especially in regions with soft soils. Soft soils are characterized by low bearing capacity, which poses a challenge for constructing stable foundations. Various soil stabilization techniques, such as mechanical, chemical, and geosynthetics, have been applied to improve the strength and stability of foundations in these soils. The effectiveness of each technique depends on factors like the type of soil, environmental conditions, and the intended use of the structure. Mechanical stabilization methods, such as compaction and dynamic consolidation, are widely used to improve soil density and shear strength. Chemical stabilization, using materials such as lime, cement, and fly ash, increases the soil’s resistance to water and enhances its load-bearing capacity. Geosynthetics, including geotextiles and geomembranes, are used for reinforcement and drainage, further improving soil stability. This paper reviews the impact of various soil stabilization techniques on the performance of foundations in soft soils, emphasizing the improvements in structural integrity. The research also explores the potential for integrating multiple techniques for enhanced results, highlighting the advantages and limitations of each approach. A critical analysis of case studies and experimental results is presented, demonstrating the feasibility and efficiency of these techniques in real-world applications. This research aims to provide a comprehensive understanding of soil stabilization methods and their contributions to improving foundation performance, with a particular focus on the long-term sustainability and cost-effectiveness of these techniques. The findings will aid engineers in selecting appropriate stabilization methods based on site-specific conditions, leading to more durable and cost-efficient foundation systems.
