Abstract: In this paper, the mechanism and influence factors of combined reinforcement of pressure dispersed ground anchor and retaining wall are analyzed by the numerical simulation on a practical example. The results show that the pressure dispersed ground anchor can strengthen the soil slope by applying the prestress of the ground anchor to the soil between the retaining wall and the anchor plate. As the height of the retaining wall decreases and the number of the ground anchor increases, the soil pressure decreases and the stability of reinforcement effect increases. When the anchor bolt is set in the middle of the retaining wall, the reinforcement effect is the best.
