The invention discloses an FRP/steel composite constraint UHPC anchor plate and a preparation method thereof, relates to the field of porous anchor plates for prestressed concrete structures, and aims to solve the technical problems that an existing anchorage device is large in weight and needs durable protection. The FRP/steel composite constraint UHPC porous anchor plate is provided by adopting a fiber reinforced resin matrix composite (FRP) with high strength and durability characteristics as a constraint material; a frustum-shaped steel pipe is adopted as a composite constraint material, an ultra-high performance concrete (UHPC) material is adopted as a local pressure stress material, and the novel anchor plate device is applied to common prestressed concrete structure engineering and has the characteristics of light weight, high strength and durability. 一种FRP/钢复合约束UHPC锚板及其制备方法，涉及预应力混凝土结构用多孔锚板领域，本发明要解决现有锚具重量大、需耐久防护的技术问题，本实施方式中提供一种FRP/钢复合约束UHPC多孔锚板，采用了纤维增强树脂基复合材料(FRP)高强、耐久特性作为约束材，采用锥台形钢管作为复合约束材，采用超高性能混凝土(U
