In Geotechnical Engineering, the bearing capacity and settlement are two main criteria that control the design and performance of footings. Due to heavy loads and non-availability of good construction sites, so engineers are usually required to place footings at close spacing. Therefore, the footings in the site generally interact with each other to some extent. There is a need for a technique which will allow the geosynthetics to increase the bearing capacity of soil without the occurrence of huge settlements. To decrease the objectionable influence of interference on the performance of the closely spaced footings, the foundation soil is reinforced by geo-grid layers. A number of investigations have been performed numerically as well as experimentally to determine the interference effect of two nearby shallow foundations subjected to vertical load with unreinforced and reinforced soil. The aim of present research work is to investigate the behaviour of settlement of two closely spaced rectangular footing resting on unreinforced silty sand and reinforced silty sand with different spacing ratio(S/B), loading condition that is concentric loading and . The model tests have been conducted using rectangular footing at different spacing ratio. The average relative density kept up throughout all the tests. The silty sand is reinforced by multiple layers of geogrid. The settlement of silty sand with rectangular footing will compute by Load- settlement curve.
