A method has been proposed to obtain the pressure-settlement characteristics of strip footings resting on layered reinforced sand based on constitutive laws of soils. The confining effect of the reinforcement provided in the soil at different layers has been incorporated in the analysis by considering the equivalent stresses generated due to friction at the soil-reinforcement interface. The prerequisite of the method is the value of ultimate bearing capacity of reinforced layered soil, which can be obtained from an empirical method proposed for the same. The value of settlement may be read directly from pressure-settlement curves for the given pressure intensity. Therefore, the strip footing resting on layered sand can be proportioned satisfying shear failure and settlement criteria.
