摘　　要：水泥混凝土构件中利用纤维材料替代钢材,不但可以起到增强效果,还可以有效避免钢筋锈蚀的发生。本文利用我国自主研发的玄武岩纤维网对海砂水泥基薄板进行增强,试验结果表明,玄武岩纤维网的抗拉强度决定了水泥基薄板的拉伸强度,随纤维网层数的增加薄板拉伸强度大幅提高,纤维网增强薄板的拉伸强度略低于钢丝网增强薄板,但延性较好;利用玄武岩纤维网增强的薄板其弯曲韧性和抗弯承载力均优于钢丝网增强薄板,且相应的指标显著高于规范要求。The use of fiber materials instead of steel in concrete components,not only can enhance the strength,but also can effectively avoid steel corrosion. This paper used basalt fiber net that independent research and development in China to reinforce the sea sand cementitious thin plate. Results show that： the tensile strength of thin plate depend on the tensile strength of basalt fiber net; as well as increased the fiber net layers,the tensile strength of thin plate greatly improved; the tensile strength of fiber reinforced thin plate is slightly lower than steel net reinforced thin plate,but better in ductility. The flexural toughness and flexural capacity of basalt fiber net reinforced thin plate are better than steel net reinforced thin plate,and its equivalent wind load was significantly higher than the specification requirements.
