Abstract: Aimed at the design of distribution layer in defense works, the status and problems involving distribution research were summarized and analyzed. The perfect distribution layer should be safe, economical, practicable, and reliable, and have enough static compressive strength and good resistance to the impact, which should weaken the stress wave strength and absorb the energy deriving from explosion to the greatest extent under the condition of repeated impact loadings. And some issues that need to be resolved and the development tendency in the design of distribution layer were discussed. The results show that the main materials in the distribution layer are still concrete or soil at the present stage and days to come, and the perfect structure should be the combination of layered structure and cavities-contained structure. All those could give a reference to the design of advanced distribution layer in defense works.
