摘要
对强制电流阴极保护下氯离子在钢筋混凝土结构中扩散进行了有限元数值模拟;通过建立阻盐系统的数学模型,计算比较了不同电场下特定区域的氯离子浓度,研究了电场、氯离子浓度之间的相关性,从而为阻盐防护技术的实施提供依据。
Through a numerical simulation for chloride retardation technique,the diffusion of chloride ion in reinforced concrete structure can be retarded by the electromigration effect induced by the external electric field.By comparing concentrations of chloride ion in specified region under different electric fields,the relationship between the concentration and electric potential is studied,so as to support the implementation of this chloride retardation technique.
