Abstract: Settlement parameters of shallow foundations placed on clayey soils have been studied in PortHarcourt City of Nigeria. Fifty soil samples were obtained from six locations and subsequently subjected to oedometer tests. Settlement parameters of void ratio,e, coefficient of volume compressibility, mv, and compression modulus, Ec, were deduced from oedometer results. Results of e, and mv generally showed a decreasing trend with increase in pressure, while Ec increases with pressure. Predictive models relating void ratio and pressure, coefficient of volume compressibility and pressure, and that of compression modulus and pressure, were subsequently formulated. The generated models can be used for quick evaluation of settlement input parameters required in settlement analysis of foundation placed on cohesive soil formation.
