Abstract
Various parameters are effective in the stability of soil-nailed walls, one of which is the nail angle relative to the horizontal surface (θ). In this paper, first, a two-dimensional (2D) numerical model of a soil-nailed wall in Seattle, Washington, was simulated. Then, to validate the results obtained from the numerical simulation, they were compared with the results obtained from a previous study. Finally, the effect of θ on the behavior of the soil-nailed wall in deep excavations during earthquake excitation was investigated. The results showed that as the value of θ increased, the maximum value of surface settlement increased, so that at θ = 25°, the maximum value of surface settlement was about 75% more than that of a nail with θ = 15°. The simulation results indicated that among the values of θ investigated, θ = 15° resulted in the best performance of the wall.
