摘 ? 要：通過研究硅灰、Ⅰ級粉煤灰及S95礦渣粉摻量及摻入方式對高性能混凝土（HPC）的影響，確定了Ⅰ級粉煤灰和S95礦渣粉以1∶1復摻制備HPC預制裝配式電纜溝。針對不同服役條件，設計了預制HPC電纜溝U型截面形式，并對其承載力進行了試驗驗證。結果表明：預制HPC電纜溝的關鍵部位強度及變形均滿足承載力及變形要求，可為電纜溝的預制裝配化應用提供參考。 Abstract: According to the influence of silica fume, grade Ⅰ fly ash and S95 slag powder on the performance of high performance concrete (HPC), it is determined that the best mix proportion of grade Ⅰ fly ash and S95 slag powder is 1∶1. For different service conditions, the U-shaped section of HPC prefabricated cable trench is designed and prepared, and the bearing capacity is verified by simulation and test. The results show that the strength and deformation of key parts of HPC prefabricated cable trench can meet the requirements of bearing capacity and deformation, which can provide a reference for application of ?the prefabrication and assembly process of cable trench.

摘 ? 要：為實現裝配化、生態化和景觀化，從結構設計和生態設計出發，提出了一種新型預制混凝土生態組合護岸制品，重點介紹了該類護岸制品的連接構造、結構配筋、生態倉布置，最后基于實際工程，介紹了其生產流程和應用效果，以期豐富水利工程護岸的結構形式，提高相應工程的社會和經濟效益。 Abstract: In order to realize the aim of assembly, ecology and landscape, a new type of precast concrete ecological composite revetment is proposed from the structural design and ecological design. The connection structure, structural reinforcement and ecological bin layout are mainly introduced. Finally, based on the actual project, the production process and application effect are introduced, so as to enrich the structural form of the revetment of water conservancy projects and improve the social benefit and economic benefits of the corresponding projects.
