摘　　要：通过对钢筋混凝土桥面板表面氯离子浓度的测量,并运用超越方程预测钢筋混凝土桥面板锈蚀的开始时间,即采用三种不同表面氯离子的浓度-时间关系曲线,根据不同的扩散系数和混凝土层深度对锈蚀开始时间进行预测,这对于桥面板的维护和修复有重要的参考价值。It can use transcendental equations to predict the corrosion initiation bridge decks based on the measured surface chloride concentration. That is three types concentration and initiation time relationship curves can be used, with computing of the time of of surface different values of the diffusion coefficient and the concrete cover, whose results have important value for bridge deck maintenance and rehabilitation. concrete chloride time by reference
