    摘要:

    玄武岩纤维混凝土(BFRC)在抗冲击与抗爆工程领域应用前景广阔,但其动载作用下的力学试验研究尚缺乏系统梳理。本文从试验方法与机理分析两个维度,对BFRC动态抗拉和抗压力学特性的研究进展进行了综述。内容涵盖宏观试验与微观表征两个层面,并系统归纳了试验差异、影响因素、测试方法和主要结论。结果表明:在恒定应变率下,随着玄武岩纤维掺量和长度的增加,BFRC的抗压强度和动态增长因子均呈现先增后减的变化规律;当纤维掺量为 0.2%、长度为 6 mm 时,BFRC力学性能达到最优。区别于现有综述,本文提出应构建BFRC“宏-微观”多尺度协同试验框架,凝练跨尺度结果的内在关联机制,并对试验检测一体化、数据智能解析与试验标准化进行了展望。本文成果可为动载作用下的玄武岩纤维混凝土力学试验研究提供借鉴与参考。

    Abstract:

    Basalt fiber concrete (BFRC) has broad potential applications in the fields of impact resistance and explosion resistance. However, there is a lack of systematic research on its mechanical behavior under dynamic loads. A review of the research progress on the dynamic tensile and compressive mechanical properties of BFRC is provided from two perspectives: experimental methods and mechanism analysis. The content covers both macro-scale experiments and micro-level characterization, and systematically summarizes the differences between experiments, influencing factors, testing methods, and key findings. The results show that, at a constant strain rate, as the content and length of basalt fibers increase, both the compressive strength and the dynamic growth factor of BFRC exhibit a pattern of first increasing and then decreasing. When the fiber content is 0.2% and the fiber length is 6 mm, the mechanical properties of BFRC reach their optimal values. Unlike existing reviews, this paper suggests that a "macro-micro" multi-scale collaborative testing framework for BFRC should be established. It aims to identify the underlying relationships between results across different scales, and also provides prospects for integrating testing and detection processes, intelligent data analysis, and standardization of experiments. The results obtained in this paper can serve as a reference for the mechanical testing studies on basalt fiber concrete under dynamic loads.
