乐天溪特大桥钢纤维混凝土应用研究

Study on Application of Steel Fibre Reinforced Concrete in Letianxi Big Bridge

结合三峡工程对外交通专用公路乐天溪特大桥钢纤维混凝土的应用,综合分析了钢纤维混凝土材料的性能及其在公路桥梁中的应用,提出了在工程中应用时各组成材料的合理选择、配合比设计方法及施工工艺,通过试验研究,为该工程提供了合理的配合比。

With the application of steel fibre reinforced concrete (SFRC) to Letianxi Big Bridge of special highway of Three Gorges Project, this paper analyses the characteristic of SFRC and the application of. SFRC in the highway bridge. Proper selection of raw materials, designing method of proportion of mixture and construction method of SFRC are provided for engineering application. Through the experimental research, the mix proportions of SFRC are found.
