Numerical & Experimental Analysis for Soil Subgrade Strength Improvement Using Geosynthetics

Abstract

The construction sector widely utilizes soil, a substance known for its adaptability. All civil engineering constructions rely on soil for support, whether they rest on it or immerse in it. Soil poses significant obstacles during construction due to its great compressibility and diversity of characteristics. External materials like geosynthetics frequently implement soil stabilization to tackle these problems. The loading process has an impact on the soil's microstructure, which affects the performance of structures. The purpose of this study is to investigate how soil foundations behave in different situations, focusing on how stress is distributed and how structures change shape, with and without geosynthetic material. In this context, computational techniques are used, specifically Abaqus FEM software, to simulate soil foundations and analyse various scenarios that involve boundary conditions, mechanical loading, and stress distribution. Initial findings suggest that using geosynthetic materials in the soil subgrade results in enhanced stress distribution and less deformation.
