    摘要:

    分析了纤维编织网和混凝土之间应力传递的机理,通过拉拔试验探讨了纤维束埋长、表面处理情况、混凝土强度和工作性能以及预应力水平对纤维编织网和混凝土粘结性能的影响.试验结果表明:随纤维埋长增大,纤维束的最大拉拔力不断增大,由脱粘破坏向拉断破坏转变;提高混凝土强度、改善其工作性能、用环氧树脂浸渍纤维编织网以及对其施加预应力均能提高纤维束的粘结强度.

    Abstract:

    The mechanism of bond that the stress is transferred from fine concrete to textile is reviewed,and the influences of initial bond length of textile,surface treatment of textile,strength and workability of concrete as well as level of prestressing force on bond behavior were investigated on the base of pull-out tests.The results show that with initial bond length increasing,the maximum pull force increases and the failure of fibre changes from debonding to rupture.Increasing concrete strength and improving workability of concrete mix,epoxy resin impregnating of textile as well as prestressing textile can significantly increase bond strength between textile and concrete.
