为了研究腐蚀环境对钢绞线与混凝土间黏结性能的影响，将钢绞线与混凝土黏结试样分别置于4种不同腐蚀环境中进行电化学加速腐蚀，得到腐蚀后试样的黏结应力-滑移曲线，并与未腐蚀试样进行了对比分析。结果表明：相同腐蚀时间下，各腐蚀环境对黏结性能影响从大到小依次为氯化钠溶液、模拟酸雨、硫酸钠溶液、硝酸钠溶液；随腐蚀时间的延长，试样的腐蚀程度加剧，黏结强度及黏结刚度不断减小，但都比未腐蚀试样的大。轻微腐蚀时，腐蚀产物对极限黏结强度有提高作用，且在硝酸钠和硫酸钠溶液中腐蚀后试样的极限黏结强度分别为未腐蚀试样的2.56倍和2.35倍，明显高于在模拟酸雨和氯化钠溶液中腐蚀后试样的，但黏结性能总体变化不大。

In order to research the effect of corrosive environment on the bonding behavior between steel strand and concrete, the curves of bonding stress vs slip of the specimens of steel strand bonded with concrete in four different corrosive environments were obtained by electrochemical accelerated corrosion test, and were analyzed by comparison with that of the uncorroded specimen. The results show that the influence order of corrosive environment on the bonding behavior from big to small was sodium chloride solution, simulated acid rain, sodium sulfate solution and sodium nitrate solution for the same corrosion time. With the prolongation of corrosion time, the corrosion degree increased, the bonding strength and bonding stiffness all decreased, but they were still larger than that of the uncorroded specimen. In mild corrosion, corrosion products improved the ultimate bonding strength. The ultimate bonding strengthes of the specimens corroded in sodium nitrate solution and sodium sulfate solution were 2.56 times and 2.35 times higher than that of uncorroded specimen, respectively, and were obviously higher than those of specimens corroded in simulated acid rain and sodium chloride solution, but the bonding behavior of different specimens was not changed much.
