| Abstract | Several researchers have studied the effects of various important parameters like number of layers of reinforcement (N), depth of the upper most layer of reinforcement from the base of the footing (u), spacing of the reinforcement layers (h), width of reinforcement layer (b), tensile strength of reinforcement (T) and density of soil (γ) on the ultimate bearing capacity of footings on reinforced soils. However, very few of them have attempted to develop equations to estimate the bearing capacity of the footings on reinforced soils by considering all the above parameters. Review of the existing state of the art in this area is presented in this paper and the ability of the existing analytical models to predict the ultimate bearing capacity of reinforced sand beds is verified using results from laboratory model tests. A multiple regression equation to estimate the ultimate bearing capacity of square footing resting on geosynthetic reinforced sand beds based on the laboratory model studies is presented. This equation is verified against the experimental results of model studies and also with the experimental measurements of other researchers. Statistical analysis of the model test data revealed that the aperture size of the reinforcement is very influential in altering the bearing capacity of reinforced sand beds. The regression equation developed in this study is reasonably good in predicting the bearing capacity of square footing on dense sand reinforced with planar geosynthetics. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
