Case Study: Geotechnical Stress-Deformation Analysis of Soft Soil

This case study presents a geotechnical simulation of a real-world stress-deformation scenario involving a cylindrical water tank placed on a multi-layered soil profile consisting of soft clay overlying plastic marl, with a water table at 6m depth. The analysis, performed using GeoStudio, considers the effects of surcharge and water table on soil settlement, vertical stresses, and excess pore water pressure under both short-term and long-term conditions. The construction process is staged, including soil stabilization with granular fill, foundation placement, tank assembly, and water filling. The study employs finite element analysis and numerical methods to visualize soil settlement and determine changes in vertical stresses and pore water pressure, referencing key soil mechanics principles and relevant literature to support the analysis and interpretation of results.
