| 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.

| 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 affect the safety and suitability of a bridge structure.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. |
