摘要: 砼结构在长期自然环境和使用条件下会逐渐老化、损伤甚至破坏,影响结构物使用功能和安全,因此,结构耐 久性是工程结构可靠性的重要内涵之一.在设计砼桥梁时,除了进行承载力计算、变形和裂缝验算外,还应在设计上 考虑耐久性问题

关键词: 砼桥梁, 耐久性状况, 耐久性设计

Abstract: Concrete structures will be deteriorated and damaged because of the natural environment and the long-term usage. The deterioration of the structural behavior and the damage inside the structure always afect the safety an d suitability of a bridge secture.Therefore,the durability of structure is one of the important objectives for the reliability of engineering structures.In design calculations,besides considering bearing capacity,flexibility control and crack control,durability design must be considered.

Key words: concrete bridge, durability status, durability design
