In some projects, such as the foundations of high-rise buildings adjacent the excavation, bridge abutments and tower footings for electrical transmission lines, foundations may be built on a slope. In these cases, the behavior of the mentioned foundation will be affected by the slope. In this study the results of a series of numerical analyses using finite element method on strip footing rested on both reinforced and unreinforced soil slopes were presented. The developed model was validated by some of the existing theories. Afterwards, the parametric studies were performed to determine the geometrical effective parameters and their effects on the behaviour of this type of footing. Results indicated that the bearing capacity of footing can be considerably improved by the inclusion of reinforcing layer and amount of improvement is function of the depth and spacing of reinforcement layers, slope angle and distance of footing from the slope. By evaluate the effect of number of geogrid layers it was found that significant increase in the bearing capacity is occurred by increasing the number of geogrid layers up to four layers.
