Abstract
In this paper the behavior of an artificial slope, during a cyclic loading, is investigated by utilizing shaking table test and numerical simulation obtained from a finite element analysis. The effects of rock bolts and rope nets, used to stabilize the slope during earthquake, are investigated in several experimental and analytical cases. The slippage between rock bolt and soil is simulated by a nodal link element, placed at the contact area of rock bolt and soil. Using rock bolts and rope nets as reinforcement, affect the response of the model by reducing the maximum displacement of the slope along with a considerable decrease in maximum tensile stress. The developed cracks at the top of slope are also modeled with link element. When the cracks open, tensile stress can not develop across the opening and a tensile stress release may occur in that area which results in a redistribution of internal stresses in the slope.
