This study material on geotechnical design covers the simulation of a real-world scenario using basic knowledge of soil mechanics, finite element analysis, and numerical analysis. The effect of surcharge and preference of water table is considered during the analysis. The study problem is a stress deformation situation, and the software specified for the analysis is GeoStudio. The case study involves stabilization of soil, construction of foundation, and assembly of a water tank. The study material also covers the methodology, results, and assumptions made during the analysis.
