| 摘 要： | 为了寻求更为简单、快速的道路混凝土抗冻性测评方法，文章通过室内宏观试验研究了抗冻性与氯离子抗渗性的关系，并辅以微观试验分析了相关机理。结果表明，抗冻耐久性指数与氯离子电通量之间存在较为显著的相关关系；微观结构参数（气孔间距系数、孔级配）对抗渗性与抗冻性的影响规律较为相似，是抗冻性和抗渗性关联密切的重要原因。

| Abstract: | In ordor to find a simper and faster method for testing frost resistance,the relationship of frost resistance and impermeability of chloride is studied through indoor macroscopic test.And the mechanism is analyzed by Microscopic test.The results showed： The durable index and electric flux have relatively remarkable correlational dependence;The impacting law of micro-structural parameters（Bubble spacing factor and Pore size distribution）on the frost resistance and impermeability is quite similar. And this conclusion is thought very important for explain the phenomenon that the frost resistance having closed relationship with Impermeability. |
