摘要:

摘  要:从实验和理论角度系统研究了在动态荷载作用下,氯离子在砂浆中的传输性能。通过疲劳荷载与氯离子传输的同步实验,并采用已有损伤传输模型对实验数据进行分析。结果表明:已有的含损伤的传输模型中损伤为“静态”而非“动态”,已不再适用目前的实验工况;给出了适合于研究疲劳与氯离子传输同步进行的传输模型,此模型的预测结果与实验结果吻合很好。

Abstract: The dynamic transport performance of chloride ion in mortar was investigated from the theoretical and experimental angles. The latest results obtained by a self-designed experiment method were analyzed via a pre-existing damage diffusion model. It was found that the pre-existing diffusion model with damage factor in a static state (not in dynamic state) could not be used to describe the diffusion law of ion in mortar under simultaneously coupled action of fatigue loading. A model for chloride ion diffusion behavior under action of fatigue loading was proposed. The model can effectively predict the ion diffusion behavior under action of fatigue loading based on the present experimental method.
