化学腐蚀环境下地铁结构耐久性设计研究

Research on the Durability of Chemical Corrosive Environment of Subway Structures

化学腐蚀严重威胁着地铁结构的耐久性.通过分析地铁结构、外部环境、化学腐蚀机理,提出一种混凝土强度等级与保护层厚度相协调的应对地铁耐久性问题的办法.

Chemical corrosion is a serious threat to the durability of subway structure. Based on the analysisof the structure, the external environment and the chemical corrosion mechanism, a method for the coordinationof the concrete strength grade and the thickness of the protective layer is proposed.
