摘要
根据侵蚀环境中离子迁移特点和化学反应机理,在考虑侵蚀离子在水泥土中的扩散、渗透和化学反应的基础上建立了侵蚀环境中离子迁移的模型,并求得模型的解析表达式。模型可根据侵蚀离子的不同条件求得其解,为各种侵蚀环境中的离子迁移提供了理论依据,同时对水泥土进行耐久性评估、剩余寿命的预测和耐久性设计的依据,具有重要的理论意义和现实意义。
According to ion migration characteristics and chemical reaction mechanism in erosion environment,considering diffusion,permeation and chemical action of erosive ion in soil-cement,this paper establishes ion migration model in erosion environment and gives analytical expression of this model.The solution of this model may be obtained based on different conditions of erosive ion,which provides theoretical basis for ion migration in erosive environment.Meanwhile,this paper carries out evaluation on durability,prediction on remaining life and basis on durability design,which has important theoretical significance and practical significance.
