摘　　要：文中以某项目纤维喷射混凝土边坡支护为背景,考虑粉煤灰、减水剂及聚丙烯纤维的影响对纤维喷射混凝土进行优化设计。结果表明:粉煤灰最佳掺量为胶凝材料质量的20%,减水剂最佳掺量为0.8%,聚丙烯纤维最佳掺量为1.0kg/m^(3);以FC20F10S8作为纤维喷射混凝土的的配合比,能够达到工程质量要求,且回弹率仅为7.6%。In this paper, taking the fiber shotcrete slope support of a project as the background, the influence of fly ash, water reducer and polypropylene fiber is considered to optimize the design of fiber shotcrete. The results show that the optimum content of fly ash is 20% of the mass of cementitious material, the optimum content of water reducing agent is 0.8%, and the optimum content of polypropylene fiber is 1.0kg/m^(3);Using FC20F10S8 as the mix proportion of fiber shotcrete can meet the requirements of project quality, and the rebound rate is only 7.6%.
