摘要

    摘要
  • 摘要: 玄武岩纤维是一种环保高性能的无机材料。玄武岩纤维混凝土所具有的增强、增韧、阻裂等性能,对于控制软弱围岩隧道的变形具有重要的力学优势。通过钢筋混凝土和玄武岩纤维混凝土衬砌力学行为室内模型试验,对玄武岩纤维混凝土衬砌的承载特性进行研究。研究结果表明：相比钢筋混凝土,玄武岩纤维混凝土衬砌的初裂荷载提高了20%;掺入玄武岩纤维后衬砌结构的韧性增强,衬砌初裂后仍可承担较大的弯矩和变形。衬砌初裂前,钢筋混凝土和玄武岩纤维混凝土衬砌支护特性曲线基本成线形变化;衬砌初裂后,钢筋混凝土衬砌支护特性曲线在缓慢上升后,快速趋于收敛;玄武岩纤维混凝土衬砌承载特性曲线缓慢上升,至2倍初裂荷载时仍无收敛迹象。因此,玄武岩纤维混凝土能较好地满足软弱围岩隧道尽早封闭岩面、尽快提供支护力并具有一定变形能力的要求。研究成果对于软岩大变形隧道的变形控制具有重要的意义。
    Abstract: Basalt fiber is a kind of inorganic material, which is effective and environmentally friendly. Basalt fiber concrete has important mechanical advantages to control the deformation of soft rock tunnels because it has functions such as strengthening, toughening, crack resistance and so on. Through the indoor model tests on mechanical behaviors of reinforced concrete and basalt fiber-reinforced concrete, the bearing characteristics of lingings of basalt fiber concrete linings are investigated. The test results show that compared with that of the reinforced concrete lining, the initial crack load of the basalt fiber concrete lining increases by 20 percent. The lining structure gets tougher after it is mixed with basalt fiber, moreover, after occurrence of the initial crack, the linings can also bear larger bending moment and deformation. The bearing characteristic curves of linings of the reinforced concrete and basalt fiber concrete exhibit linear change before the initial crack. After the initial crack, the curve of the reinforced concrete rises slowly before rapid convergence. The curve of the basalt fiber concrete increases to two times the value of the initial crack load and there is no convergence trend. Therefore, the basalt fiber concrete can satisfy both the requirements that the rock surface of the soft wall rock tunnel should be closed as soon as possible and the linings can provide supporting force with a certain deformation ability as soon as possible. The research results are extremely important to the control of large deformation of soft rock.
