This invention discloses a layered concrete structure with anti-penetration and filtering properties and its preparation method. It solves the problem in existing technologies where only the composition of the concrete layers is changed without improving the overall filtering performance. This invention has the beneficial effects of improving filtering performance and preventing further crack development. The specific solution is as follows: A layered concrete structure with anti-penetration and filtering properties includes a fiber-reinforced concrete layer and an intermediate composite material layer. The intermediate composite material layer is placed between two fiber-reinforced concrete layers. The fiber-reinforced concrete layer and the intermediate composite material layer are periodically arranged to form a layered concrete structure to enhance the filtering performance and improve the anti-penetration performance. The fiber-reinforced concrete layer contains steel fiber reinforcement to enhance the anti-penetration performance of the layered concrete structure. The wave transmittance in the intermediate composite material layer is different from that in the fiber-reinforced concrete layer, and the intermediate composite material layer is bonded to the fiber-reinforced concrete layer.
