工作环境对混凝土桥梁耐久性的影响

我国的公路混凝土桥梁建设在原材料选择、结构设计和施工技术等环节上均落后于西方发达国家，可以推断，这些桥梁今后所面临的耐久性问题将会比西方发达国家今天所面临的问题更为严重。从工作环境上对公路混凝土桥梁结构的损伤机理进行系统的研究，并提出改善混凝土桥梁耐久性的相关措施．对于混凝土桥梁耐久性研究具有一定的参考价值。

Working Conditions＇ Effect on Durability of Concrete Bridge

Chinese road concrete bridge construction falls behind the western developed countries in the raw material choice, structural design and construction technology and so on. In this context, the durability problems are more serious than those of the developed countries today. The damage mechanism of the road concrete of bridge structure from working conditions is studied and some related improvement measures of the durability of concrete bridge are proposed, which have a certain of reference value to durabili...
