纤维编织网与混凝土能否协调工作取决于两者之间的黏结强度。通过拉拔试验,分析了纤维束埋置长度对纤维网与混凝土黏结性能的影响,分析了纤维编织网与混凝土之间应力传递的机理。试验结果表明:随纤维束埋长增长,纤维束的极限拉拔力不断增加,平均黏结强度降低。最后提出了最佳埋置长度的取值和基本锚固长度的计算公式。
Whether textile and concrete can coordinate with each other is related to their bond behavior.The influence of initial bond length on bond behavior between textile and concrete was investigated based on the pull-out tests.Meanwhile the mechanism of the bond stress how is transferred from concrete matrix to textile is reviewed.The results showed that the ultimate pull force increases and the average bond strength declines with the enhancement of initial bond length.Finally the best value of initial bond length and the formula of basic anchorage length are recommended in this paper.
