Performance of square footing under the axial and eccentric loading on reinforced Non cohesive soil by geotextile : an experimental investigation

Civil engineering

There are several approaches available to enhance the bearing capacity of soil, but soil reinforcement stands out as a well-established and commonly employed method, especially for footings. In this study, we aim to investigate the performance of square footings using non- cohesive soil, deviating from the typical sand-based cohesive soil often used in experimental studies. The experimental setup will consist of a 500X500X450mm tank, equipped with essential instruments including a dial gauge, proving ring, and mechanical jack. Our focus will be on examining the impact of eccentricity in scenarios where axial or central loads are applied to square footings. We will conduct a comparative analysis, looking at cases both with and without the incorporation of GeoFibres, to assess their influence. Ensuring a stable foundation is of utmost importance for structural stability and resistance. However, achieving this stability can be challenging due to varying soil conditions. Therefore, it is essential to evaluate how a foundation settles on different soil types before embarking on actual construction. The proposed model serves as a valuable tool for such assessments. By introducing GeoFibres as a reinforcement measure, we aim to improve the soil's load-bearing capacity. We will conduct tests under varying conditions, with and without GeoFibres, and subsequently, comprehensively analyze and compare the results to gain valuable insights.
