Geotechnical Analysis and Design Report: Circular Oil Tank Foundation

This geotechnical report presents an analysis of a circular reinforced concrete oil tank founded on a specific soil profile, focusing on bearing capacity, settlement, and consolidation. The analysis utilizes Optum G2 software to model the soil behavior and tank loading conditions. The report addresses short-term and long-term bearing capacities, calculating factors of safety. It investigates initial and total settlements, including elastic and elastoplastic components, and determines the time required for 80% consolidation. Furthermore, the report explores methods to decrease the final settlement of the tank by 25%, proposing and analyzing alternative foundation designs such as increasing the base diameter and soil replacement with stiffer clay. Contour plots of excess pore water pressures are provided to visualize consolidation behavior. This report provides a comprehensive analysis of the geotechnical aspects of the oil tank foundation, offering valuable insights into its design and performance.
