摘　　要：对定向钢纤维混凝土制备方法、纤维分布特征、纤维分布调整以及试件动/静力学性能进行了系统阐述。重点对国外研究人员基于细观纤维拉拔本构模型,构建考虑纤维分布特征的钢纤维活性粉末混凝土本构模型的方法进行了梳理;对国内研究人员近年提出的以均匀磁场调整钢纤维分布进而制备定向钢纤维混凝土的方法以及定向钢纤维混凝土的力学性能与纤维分布特征的关系进行了总结。在此基础上展望了磁场制备定向钢纤维混凝土基于细观力学的本构模型、纤维分布特征的表征方法以及动/静力学性能研究的前景。In this paper, the preparation methods of aligned steel fiber reinforced concrete , fiber orientation characteristics, fiber distribution adjustment, and dynamic/static mechanical properties of ASFRC specimens are systematically expounded. The steel fiber reactive powder concrete constitutive model constructed by foreign researchers based on single fiber pullout constitutive model, which takes into account the fiber orientation characteristics, is hackled. What＇s more, preparation method of aligned steel fiber reinforced concrete via uniform magnetic field, which was put forward by the domestic researchers in recent years, and the relationship of ASFRC mechanical properties and fiber distribution characteristics are summarized. On the basis of the above discussion, the researchers of the constitutive model of ASFRC based on micro-mechanics, the characterization of fiber distribution and dynamic/static mechanical properties are prospected.
