摘要： 近年来，随着我国国民经济的迅速发展和对建筑结构质量需求的提高，纤维增强水泥基复合材料(Fiber Reinforced Cementitious Composites，简称FRCC ) 以及超细晶高强钢筋在我国的工程实际中开始得到一定规模应用和一定程度的推广，国内对使用这些新型材料结构的受力性能研究也有所加强。到目前为止，我国关于超细晶钢筋增强FRCC构件受力性能的研究尚相当缺乏，对超细晶钢筋增强FRCC构件的研究也与发达国家存在较大差距，加强对纤维增强水泥基复合材料及超细晶高强钢筋性能及应用研究很有必要。本文就超细晶钢筋及FRCC在人防工程结构中的应用展开了相关研究，通过技术经济分析表明超细晶钢筋及FRCC新型材料有很好的应用前景。

Abstract: in recent years, with the rapid development of China''s national economy and the structure quality demand increase, Fiber Reinforced cement base composite materials (Fiber Reinforced Cementitious couldn''t be examined hereinafter referred to as the FRCC) and super fine grain in our country of high strength steel in engineering practice began to get certain scale applications and a certain degree of promotion, domestic to use these new materials structure of the force performance study also has been improved. So far, our country about super fine grain reinforced enhance FRCC component force performance is still quite lack, for the fine grain reinforced enhance FRCC component research also has a large gap with developed countries, to strengthen the fiber reinforced cement base composite materials and super fine grain high strength reinforced performance and application research is necessary. This paper is super fine grain reinforced and FRCC in the application of civil air defense projects structure on the related research, through the technical and economic analysis shows that the super fine grain reinforced and FRCC new materials have a good application prospect.

Keywords: super fine grain reinforced, FRCC, protection engineering, the application prospect

1.1 超细晶超强钢筋

1997年4月，在日本科技厅的支持下日本开始了“新世纪结构材料（超级钢材料）”为期10年的研究计划，提出将现有钢材使用寿命翻番和强度翻番为目标的新一代钢材，称其为“超级钢”并在国家组织下开展研究[1]。之后韩国在1998年启动了“21世纪结构钢的研究计划”，我国在1998年10月启动了“新一代钢铁材料”的国家重大基础研究计划（973），计划将占我国钢产量60 %以上的碳素钢、低合金钢和合金结构钢的强度和寿命提高1倍。东亚三国相差不到一年，设立相同目标的研究项目带动了欧美各国钢铁界竞相参与和重视。2001年，欧盟启动了“超细晶粒钢开发”计划。……
