万州驸马长江大桥钢桥面耐久性铺装设计方案与控制指标

Durable Pavement Designing Scheme and Control Index of Steel Bridge Deck of Wanzhou Fuma Yangtze River Bridge

通过调研国内钢桥面铺装类似结构使用条件和病害情况,提出满足万州驸马长江大桥高温重载使用条件的钢桥面耐久性铺装设计方案及主要控制指标,对提高驸马长江大桥等大跨径钢桥面铺装使用寿命具有重要意义。

After investigation on the service conditions and disease conditions of similar steel bridge deck pavement structures in China,we propose the durable pavement designing scheme and main control indexes of steel bridge deck to satisfy the high temperature and heavy load service conditions of Wanzhou Fuma Yangtze River Bridge,which is of great significance to improving the service life of long-span steel bridge deck pavement such as Fuma Yangtze River Bridge.
