为避免高强不锈钢绞线网-渗透性聚合物砂浆加固层发生早期剥离破坏,保证加固层与混凝土界面的粘结性能,通过9个试件的剥离破坏试验,分析了加固层与混凝土界面剥离破坏特征,测试了加固层与混凝土粘结-滑移曲线,并通过ANSYS有限元程序建立模型,对剥离破坏试验进行数值模拟,得到了加固层粘结-滑移特征参数,建立了高强钢绞线网-聚合物砂浆加固钢筋混凝土粘结-滑移本构方程。剥离破坏试验与有限元计算的对比分析表明,建立的粘结-滑移本构方程可用于实际工程计算。

英文摘要：

For avoiding to premature debonding failure of reinforced layer made up of stainless steel wire mesh and permeability polymer mortar and ensuring the bond performance between polymer mortar and concrete, the experiments about the debonding failure between reinforced layer and concrete were carried out. The characters of the debonding failure between reinforced layer and concrete were analyzed, and the bond slip curves were tested. The program ANSYS was used to develop the finite element models for simulating the experimental studies. The experimental results were validated, and the characteristic parameters of bond-slip were gained, and the bond-slip relationship of reinforced layer was presented. The comparison analysis on the debonding failure test and numerical simulation shows that the bond-slip relationship can be used to calculate the practical engineering problems. 2 tabs, 8 figs, 11 refs.
