摘　　要：基于近年来国内外对纤维混凝土材料力学性能研究现状,本文对纤维混凝土衬砌力学及抗震性能的发展进行阐述和分析。首先,将纤维混凝土按照掺入短切纤维材料不同分为钢纤维混凝土、碳纤维混凝土、聚丙烯纤维混凝土、玄武岩纤维混凝土以及混杂纤维混凝土;其次,从材料力学和抗震性能两方面分析了短切纤维的掺入对混凝土材料性能及隧道衬砌结构性能的影响。结果表明,在混凝土中掺入单一纤维或混杂纤维,能够使材料的各项基本性能显著提高,同时其抗震性能也得到了明显的改善。Based on the status quo of research on the mechanical properties of fiber concrete materials at home and abroad in recent years,the development of the mechanics and seismic performance of fiber concrete linings is elaborated and analyzed.First,the fiber concrete is divided into steel fiber concrete,carbon fiber concrete,polypropylene fiber concrete,basalt fiber concrete and hybrid fiber concrete according to the materials mixed with chopped fiber.Next,the chopped fiber concrete is analyzed in terms of material mechanics and seismic performance.The influence of the incorporation of fibers on the properties of concrete materials and the structural properties of the tunnel lining.The results show that mixing single fiber or hybrid fiber in concrete can significantly improve the basic properties of the material,and its seismic performance has also been significantly improved.
