Abstract
In the present study, pile foundation underneath a single structural unit of a 90 MLD Sewage treatment plant is considered. The optimum configuration of pile arrangement with respect to number and spacing of piles for constant parameters of embedment depth of pile and subsoil characteristics and varying parameters of diameter of pile, eccentricity of loading, and pile material are investigated by using ETABS and SAFE softwares. The optimization, in terms of axial loads and slab stresses obtained, is considered for piles embedded in stratified soil with lower depths of pile shaft socketed in weathered rock, which has not been studied here to fore. Optimum pile configuration was found to be different than that which was originally provided for the considered structure. Next it was found that the endeavor to analyze pile foundation was justified in the case of provision of lesser number of piles and light-weight structural concrete but not for variation of pile diameter.
