EFFECT OF DEPTH OF FOOTING AND WATER TABLE ON BEARING CAPACITY OF FOUNDATION SOIL: A CASE STUDY

Civil Engineering

Soil is a universally occurring natural element formed due to continuous denudation of different sorts of rocks and minerals. Each type of soil inherits a lot of similar characteristics from its parent rock like chemical composition, physical appearance, color, texture etc. In spite of these, there are yet a lot of other important characteristics that significantly comes into play in the construction sector and civil engineering. The bearing capacity is the most important soil property which governs the design of foundation soft clay strata and is often unable to bear the load transferred from the super structure to the foundation. Bearing capacity and settlement are the two important parameters in the field of geotechnical engineering as bearing capacity is affected by various factors like dimensions of footing, shape and type of loading etc. This report discusses the influence of depth and water table on the bearing capacity of footing for G+3 commercial building. The analysis is a case study from India which involves initially finding index and physical properties of soil collected from the residential area of Nasik city. The study performed gives a detail study on the variation of contact pressure and load bearing capacity of underlying soil with respect to effect of water table. Later the analysis has been performed for the varying depth of footing. The report also states the most economical depth that can be adopted for the same site considering water table and. The complete analysis is performed using software module ‘GEO-5’.
