RESREACH ON TWO-DIMENSION DIFFUSION MECHANISM OF CHLORIDE ION OF RC RECTANGULAR MEMBERS

摘要：

The characteristics and the applicability of the one-dimension diffusion mechanismof chloride ion are summarized. By thoroughly studying the influences of the diffusioncoefficient D,the diffusion time T,the position of steel bars,the boundary concentration ofchloride ion and the dimensions of concrete members,the two-dimension diffusionmechanism of chloride ion suitable for engineering is analyzed according to the circumstancesof the practical RC members. The model and the analytic solution of two-dimension diffusionof chloride ion are advanced correspondingly which have the advantages of explicit concepts,definite physical meanings,clear thoughts,convenient methods and applicability.
