摘　　要：玄武岩纤维(BFRP)是一种新型加固材料,具有延性好、耐腐蚀、抗高温、价格低等优点,在钢筋混凝土结构及木结构加固工程中得到了广泛应用,但在砌体结构加固工程中的研究和应用较少,尚未形成成熟的理论。通过对BFRP布加固的砌体墙进行低周期反复荷载试验,研究了采用"X"形粘贴方式和采用"#"形粘贴方式加固墙体的受力特点;在试验基础上,推导了玄武岩纤维布加固墙体的抗剪承载力计算公式,采用此公式计算得到的玄武岩纤维布加固墙体的抗剪承载力值与试验结果吻合良好。Basalt Fiber Reinforced Polymer(BFRP)is a new kind of reinforcement material and it has the advantages of good ductility, corrosion resistance, high temperature resistance and low price. It has been widely used in reinforcement projects of reinforced concrete structures and wood structures, but there are few researches and applications in masonry structure reinforcement engineering, and the mature theory has not yet been formed. Through the low-cycle repeated load experiment of masonry walls reinforced by the BFRP sheets, the mechanical characteristics of the walls reinforced by the "X"-shaped sticking method and the "#"-shaped sticking method were studied. On the basis of the experiment, the calculation formula of the shear capacity of the wall reinforced by BFRP sheets was derived. The shear capacity of the walls reinforced by BFRP sheets calculated by this formula is in good agreement with the experimental results.
