| 摘 要： | 大连长山大桥处于严寒地区的海洋环境中,混凝土结构耐久性不但要考虑海水及海洋大气的腐蚀,还要考虑冻融损伤的影响。针对长山大桥的特殊情况,对混凝土耐久性设计进行了初步探讨,并提出了严寒地区跨海桥梁耐久性设计的几点建议。

Durability Design for Changshan Bridge in Dalian |
| |
| Abstract: | Dalian Changshan Bridge locates at marine environment of cold region.Not only should the corrosion of seawater and marine atmosphere be taken into consideration for concrete structure durability,but also the influence of freeze thawing damage.Aiming at the special situation of Changshan Bridge,durability design of concrete is discussed initially and several proposals for durability design of cross-sea bridge at cold region are put forward. |
