Abstract
The tank-type bunker is the largest coal bunker in Asia currently. In this paper, the stability calculation and deformation analysis of excavation slope under different conditions are made, using the limit equilibrium method and the finite element method. The results indicate that the slope support requirements can not be met before reinforcement, and the place of stress concentration and maximum displacement is located at nook of diagonal corner and straight wall where is the reinforcement of key positions. Reinforcement was applied in the slope, by method of composite soil nail wall and bored piles + entry cupporting complex structures. The stability and deformation are satisfied with operational requirement, and the layout of reinforcement is suitable for the slope.关键词
