ABSTRACT:

In civil engineering projects soil is regarded as the most important material. Properties of soil like density, moisture content and plasticity variation depend on various factors like depth of water table, weather, loading, etc. Bearing capacity which is considered as the most important property of soil is also affected by these factors. The foundation for any civil structure is designed according to bearing capacity of the soil at the site. There are several papers where bearing capacity of the soil are determined. Various methods and theories are used for the determination of bearing capacity like Terzaghi (1943), Meyerhoff (1963), Hansen (1970), Vesic (1973) and codes like Eurocode, Indian Standard (IS) Code and many others. Various methods use various scales of safety factors so result of the bearing capacity is different in every method. This paper works on the previously published work “Investigation of Soil and Bearing Capacity in Different Site Condition, (2012)”. This paper compares the result of the bearing capacities of the soil at two sites determined by IS code 6403:1981 and Terzaghi method. This paper also compares the different factors that affect the bearing capacity of soil like shape of footing, foundation depth and depth of water table.
