摘　　要：TORRENT法是一种可以同时测试混凝土试块及混凝土实体结构空气渗透系数的无损检测方法。设计不同强度等级的混凝土,分别测试对应的抗压强度、氯离子扩散系数、电通量以及空气渗透系数。最终建立了空气渗透系数与氯离子扩散系数、电通量之间的量化关系,进而可以用一种无损的检测方式快速评估混凝土实体结构的抗渗性。TORRENT method is a new kind nondestructive method for testing the concrete air permeability of concrete block in laboratory and concrete structure.Concrete blocks of different strength grade were vibrated,and their compressive strength,diffusion coefficient of chloride ion,electric flux and air permeability were tested.Then,the quantitative relation between concrete air permeability tested by TORRENT method and diffusion coefficient of chloride ion,electric flux was established,respectively.
