摘　　要：根据Ｘ射线和化学分析结果，全面分析了混凝土中钢筋锈蚀的机理。在此基础上推算出钢筋锈蚀体积膨胀系数的理论值，并根据现场多组实测值给出钢筋锈蚀体积膨胀系数的统计结果。According to X ray and chemical analysis, the mechanism of reinforcement rust in concrete is analysed. The coefficient of rust volume expansion is deduced based on aforementioned mechanism. Moreover, according to the data surveyed in situ, statistical results of the coefficient are given.
