| 摘 要： | Fick第二定律通常被用来描述氯离子在混凝土中的扩散性质,对于Fick第二定律在钢筋混凝土结构寿命预测的应用,已经有许多学者对其进行了研究。本文总结了他们的研究成果,分别从Fick第二定律公式中的各个影响参数出发,对公式进行讨论,并且根据公式中各个参数的不确定性,提出了Fick第二定律应用发展方向,即应用随机微分方程理论建立随机模型。

| Abstract: | Fick's second law was always used to describe the diffusion properties of chloride in the concrete.For the application of Fick's second law in the prediction of the service life of reinforced concrete structures,many researchers have already made studies on this issue.In this paper,the state-of-art of application of Fick's second law is made.A discussion on the influence of each parameter is given too.And then,according to the parameter's uncertainty,the way of the future application of Fick's second law is presented,a random model will be established by using the random differential equation theory. |
