摘　　要：氯离子作为影响混凝土耐久性的主要因素,引起了国内外广大土木工程界学者的关注,特别是沿海岸线的水运工程尤为突出。目前测试混凝土中氯离子渗透性的方法较多,但对其测定的参数与评价结果存在着较大的差异。结合各种氯离子渗透性试验方法与特点,在分析比较其优缺点的同时,提出相应的适用范围和条件,以保证测试结果的科学性和可靠性,真实地反映氯离子渗透对建筑物的影响程度,供同行们参考。Chlorine ions, being an important factor affecting the durability of concrete, has attracted concern of many scholars in the civil engineering field both at home and abroad and becomes especially conspicuous in coastal marine works. There are now many methods to determine the penetration of chlorine ions in concrete, but there are great discrepancies in the measured parameters and results of evaluation. Adequate scope and conditions of application are proposed on the basis of the various testing methods and the characteristics of the testing methods for determining the penetration of chlorine ions in concrete as well as on the basis of the analysis and comparisons of the relative merits of these methods in order to ensure the scientificalness and reliability of the measured results and truly reflect the influence of the penetration of chlorine ions in structures, which may be of reference for the professionals in the same field.
