摘　　要：在混凝土内钢筋锈蚀初期,从结构开始使用到钢筋脱钝,占整个使用寿命的最大部分,因而对其锈蚀初期行为研究意义重大.对这一研究应着眼于钢筋脱钝临界点的把握.基于此对已有临界条件进行了归纳整理和初步研究.The initial corrosion stage of reinforcing steel in concrete, which is from the starting commencement of a frame to the depassivation of reinforcing steel, accounts for the most part of the frame secvice life, with the result that the study on its behaviour is of great significance. The study of initial corrosion behaviour of reinforcing steel in concrete must focus on the judgement on the critical point of steel depassivation. This paper carries out inductive arrangement and preliminary study with the existing critical conditions.
