摘　　要：层布式钢纤维、混杂纤维混凝土是一种新型的纤维增强混凝土材料,它是在经济与性能并重的基础上,选择钢纤维分层布置,或者在此基础上让有机纤维全体积乱向分布的纤维增强复合材料。通过对多年来层布式钢纤维、混杂纤维混凝土的疲劳特性进行了系统的总结,得到许多重要的规律和结论。作为一种公路路面材料,全面、深入地认识这种新型的复合材料的疲劳性能是其走向广泛应用的前提,结合多年的研究成果,介绍了这一新型材料的疲劳性能,并对已有的成果进行了简要的评价与展望。Layered steel fiber（LSFRC） and layered hybrid fibers reinforced concretes （LHFRC） are new structure forms for fiber reinforced concrete, which is on the basis of considering economy and improvement of material properties, letting steel fiber layer distributing layer by layer, or synthesis fiber three-dimensional distributing additionally. The study group had studied on fatigue properties of LSFRC and LHFRC for years. As a kind of pavement material, studying its fatigue properties absolutely is the premise of this new composite material becoming extensive use. Fatigue properties were reviewed associating the achievements of the study group, in addition, some achievements and the developing trends of this subject were also discussed.
