摘要
国内外大量桥梁破坏实例表明:混凝土结构不是由于设计强度不够而破坏,而是由于混凝土随时间劣化(耐久性不够)而过早破坏。通过对桥梁防盐冻腐蚀有关构造进行研究,并提出防撞墙、桥面铺装混凝土、主梁、盖梁等防腐构造建议。
A large amount of domestic and overseas bridge damage cases show that concrete structure Is damaged not due to unsatisfactory design strength, but that concrete degrades （unsatisfactory durability） with time passing by, which leads to early damage. Through research on anti - corrosion of salt frozen of bridge, suggestions for anti - corrosion structure like crash - resistant wall, deck pavement with concrete, girder and capping beam and so on are put forward.
