摘　　要：盐渍土的有害离子与环境多因素耦合作用下对混凝土材料造成腐蚀或损伤,引起混凝土结构性能的劣化,严重威胁各类建(构)筑物的耐久性及服役期间的安全性。本文介绍了盐渍土环境中混凝土材料被腐蚀或损伤机理;总结了近年来氯离子、硫酸盐、以及多因素耦合作用下混凝土耐久性的研究成果;并且对盐渍土的有害离子与环境多因素耦合作用下对混凝土耐久性的研究进行了展望。The concrete materials are damaged and corroded due to harmful ion of saline soil and many environmental factors, which leading to the degradation of concrete structure and threatening the duration and safety of such concrete structures. In this paper, the corrosionor failure mechanisms of concrete wereanalyzed in saline soil environment. The research results of concrete durabilityunder sulfate, chloride ionand coupled effects of multi-factors were summarized. The prospects of concrete durability under coupled effects of harmful ion in saline soil and environmental factors were also presented.
