Sponge slopes have received increasing attention due to their unique ecological advantage. Based on the three-dimensional numerical calculation model, the paper explores the influence of the position of the reservoir on the safety and stability of the slope and compares the variation characteristics of the sliding displacement and stress field of the slope. The results show that when the reservoir is built below the slope foot or at the slope top, the disturbance is relatively small, and the maximum displacement of the slope is smaller. Shear stress concentration occurs near the wall of the reservoir, and it increases and then decreases as the height of the reservoir increases. Besides, the maximum principal stress appears near the reservoir wall and the maximum principal stress decreases as the position of the reservoir increases.
