Abstract: It has been verified that key factor influencing structural durability is the defect in structural conformation and system except for the material durability. But the problem is seldom mentioned in the durability study for concrete structures. In this paper, suitable approaches and measures for the robustness, repairability, examinability and waterproofing performance of bridges are discussed to ensure the durability of con?? crete bridges.

Key words: bridges, durability , robustness, examinability, waterproof, constructability

摘要： 大量的病害实例表明,除了材料的耐久性,影响砼桥梁耐久性的关键因素是结构构造和体系上的缺陷,而目 前的砼结构耐久性研究却很少涉及这方面的内容.本文从桥梁的整体性、可修性、可检性、防水性能等角度探讨了 如何在结构设计和构造细节方面采取合适的原则和措施,以便有效地保证桥梁的耐久性能.
