BFRP抗浮锚杆力学性能研究进展

Research progress on mechanical properties of BFRP anti-floating anchor

随着大型地铁、深基坑等复杂地下工程的发展,结构抗浮问题在工程中更加重要。而采用玄武岩纤维增强复合材料(BFRP)抗浮锚筋是为良好的选择。BFRP抗浮锚筋具有抗拉强度高、耐久性和环境友好等优点,适用于复杂地质条件的地下工程抗浮技术。但目前关于BFRP抗浮锚杆的研究相对较少,对BFRP抗浮锚杆力学性能尚缺乏系统的认识。基于此,本文归纳总结了针对BFRP抗浮锚杆受力性能的研究进展,探讨了在相关试验与数值模拟方面的研究内容,分析了BFRP抗浮锚杆研究中存在的问题与缺陷,对其后期力学性能的研究提供相应的建议与思路,所得结果为BFRP抗浮锚杆的应用提供了基础。

With the developments of subway, deep excavation and other complex underground projects, the structural anti-floating problem becomes more and more important. The use of BFRP(basalt fiber reinforced polymer) anti-floating anchor bars is a good choice. The BFRP anti-floating anchor can be applied to the underground projects under complex geological conditions and climatic environment due to its high tensile strength and durability, lower cost, and environmental performance. However, there are few studies about BFRP anti-floating anchor. Therefore, the research progress on the mechanical properties of BFRP anti-floating anchor was summarized, and the related studies of experiments and numerical simulations were introduced systematically. The difficulties and defects in the studies of BFRP anti floating anchor were also analyzed. Furthermore, the suggestions on the analyses of mechanical properties were provided. The obtained results would provide a basis for the application of BFRP anti-floating anchor.
