| 摘 要： | 根据目前我国拉索型桥梁索结构的防腐体系均遭到不同程度破坏的现状,在对索结构防腐体系破坏原因分析的基础上,结合南京长江第三大桥的特点,研究了拉索的防腐系统。结果表明:选择双峰HDPE护套,及在拉索内填充具有水汽隔绝、阻蚀防腐和润滑抗磨双重作用的防腐填充物,可延长拉索的使用寿命。该研究已成功应用于南京长江第三大桥的斜拉索体系。

| Abstract: | The cable structure antiseptic systems in China are all under destructive situation at present.The destructive causes of the cable antiseptic system were analyzed for cable structures.The results showed that the lifespan of cable could be lengthen by choosing two-humped PE sheath as well as stuffing something inside the cable that had such effects as steam isolation anti-corrosion lubrication and friction-resistence.The cable antiseptic system of the Nanjing No.3 Yangtze River Bridge was developed and put to use.The system includes PE sheath,the filling materials in the cable,the antiseptic system on the assembled cable. |
