摘要

摘要: 预应力混凝土结构的盐雾侵蚀试验研究在国内外很少见。根据盐雾环境下应力状态混凝土试件的耐久性试验研究成果，阐述了在应力和盐雾共同作用下的结构破损规律，为制定预应力混凝土结构的耐久性设计规程提供建议。

Abstract: There are few experiments of PC structures under salt fog corrosion environments at home and abroad.The authors expatiate the corrosion rules of PC structure under the coaction of stress and salt fog according to the research results of durability tests. Which will provide suggestions for working out durability codes of PC structures.
