| 摘 要： | 氯盐侵蚀是码头构件结构破坏的主要原因之一,华东地区某海港服役15 a码头的结构耐久性调查结果显示,虽然该码头构件的力学性能和保护层厚度基本满足设计要求,但桩帽、横梁和纵梁构件已遭受氯盐侵蚀,产生锈涨裂缝,且各构件混凝土抗氯盐侵蚀能力存在一定差别,其中大直径管桩具有较高的耐久性.

| Abstract: | Chloride corrosion is one of the main reasons to damage wharf members.It is shown from the structure durability investigation of a wharf of some seaport in China East which being in service for 15 years,the mechanical property and protective layer thickness of wharf members basically meet the design requirement,but pile cap,cross beam and longitudinal beam members have been corroded by sodium chloride,which causes cracks and rusty stains.The anti-chloride-corrosiveness of each member is different.For instance,Raymond-pile has a higher durability. |
