One of the control and preventive measures in the stabilization of the slopes is using the resistant piles in the strengthening the ground. These resistant piles do not disorder the balance of the slopes. Using numerical and analytical methods in stabilizing the soil slopes by the help of the piles is a common method which has been studied by various researchers. The purpose of this paper is studying the effect of soil type on stabilization of the slope in pile position using PLAXIS software. The results of these analysis show that the results are different in sandy and clay soils. Thus, these results show that the type of soil is effective on the pile function and they are also effective in the ratio of the placement in the slope as well as in the impact the angle of the pile in different soils.
