钢筋混凝土构件均匀锈蚀与应力的耦合效应分析

摘要

根据钢筋混凝土锈胀动力学及金属力学化学原理，分析了在混凝土完好的条件下，钢筋应力对锈蚀反应速度的影响。通过计算,确证了均匀锈蚀条件下应力因素对钢筋锈蚀速度无显著影响。%In accordance with the corrosive dynamics of reinforced concreteand chemico-mechanical principles of metallic corrosion, the influence of stresses in reinforcing steels on corrosive reaction velocity under the condition that there is no crack in the concrete is analyzed. It is confirmed by calculation that, under the condition of uniform corrosion, stresses in reinforcing steels do not have notable effect on corrosion rate of the reinforcing steels.
