土建结构工程的耐久性与工程的使用寿命相联系,是使用期内结构保持正常功能的能力,这一正常功能包括结构的安全性和结构的适用性,而且更多地体现在适用性上。大多数土建结构由混凝土建造。混凝土结构的耐久性是当前困扰土建基础设施工程的世界性问题,并非我国所特有,但是至今尚 Durability of civil engineering works is linked to the useful life of the project and is the ability of the structure to maintain its normal function over the life of the building. This normal function includes structural safety and structural applicability, and more on applicability. Most civil structures are constructed of concrete. The durability of concrete structures is a worldwide problem currently plaguing civil engineering projects and not unique to our country, but so far
