腐蚀环境下混凝土结构的力学性能研究现状与展望

Retrospect and Prospect of Mechanical Property Study for Corroded Concrete Structures

氯离子是腐蚀钢筋混凝土结构、造成结构耐久性失效的重要因素,其对混凝土结构的危害日益明显,已引起了人们广泛的关注。较为详尽地综述了氯盐环境下钢筋混凝土结构的腐蚀机理,总结了近年来国内外学者对其静力力学性能和动力力学性能的研究,最后提出了腐蚀混凝土结构力学性能研究中存在的问题,为今后的研究工作方向提供了建议。

The chloride ion is the most important factor to corrode reinforced concrete structure,which causes the durability of structure failure.The harm of concrete structure is becoming more and more obvious,which has aroused widespread concern.This paper reviews the corrosion mechanism of concrete structure under the Chlorate environment in detail,summarizing the static mechanical properties and dynamic mechanical properties research at home and abroad.Finally puts forward the problems existing in the study of mechanical performance of concrete structure corrosion,and the direction of future research work.
