摘　　要：由于混凝土耐久性室内试验无法真实、全面地反映实体结构的性能状况,开展混凝土结构耐久性的现场无损检测,对提升结果的真实性、可靠性具有重要意义。文章通过大量调研,梳理了国内外较为常用的耐久性专项指标,并对指标的检测技术进行了整理归纳,比对了各技术的适用范围和优缺点;针对氯离子含量及抗渗透性能这类海洋环境下混凝土结构耐久性能的重要指标,介绍了适宜现场使用的无损检测技术及设备,以期为混凝土结构耐久性检测提供参考。For the concrete durability indoor test couldn＇ t reflect the real performance of concrete structure overall, so doing the non-destructive field testing technology of concrete durability is quiet important to improve the authenticity and reliability of the results. Through lots of investigations, some domestic and foreign common durability special indicators are sorted and the index testing technologies are summed up, then the application scope, merits and drawbacks of the technology are compared. For the key parameters of the concrete structures durability under marine environment, such as chloride ion content and permeability performance, some nondestructive field testing technology and equipment are introduced, which could provide reference for durability testing of concrete structures.
