海水环境下钢筋混凝土结构使用寿命的预测

Prediction of the Service Life of the Reinforced Concrete Structure in Seawater Surroundings

以菲克 (Fick)第二扩散定律为基础 ,以氯离子侵蚀为主因 ,提出了海水侵蚀情况下钢筋混凝土结构物使用耐久寿命的预测方法 ,并经过算例验证说明该预测方法对于以氯盐侵蚀破坏为主的钢筋混凝土结构物有一定意义 .

Taking the chlorion as the main corrodent,the authors put forth a method to predict the service life of the reinforced concrete structure in seawater surroundings,with Fick's second law of diffusion as the theoretic basis.Several examples confirm that this method works well for cases of the chloride salt being the main corrodent in the reinforced concrete structure.
