马鞍山长江公路大桥钢桥面铺装设计指标分析

Steel bridge deck pavement design index analysis of the highway bridge in Maanshan Yangtze River

对马鞍山长江公路大桥钢桥面铺装技术难点进行了分析,并确定了设计要求。参考国内类似结构的多种大跨径悬索桥钢桥面铺装设计指标,从使用条件、工程实践及试验研究等角度出发,对比分析了钢桥面铺装设计指标。结合该桥整体结构变形和荷载响应特性,制定了钢桥面铺装结构层设计指标。该研究成果对改善钢桥面铺装的结构性能和提高钢桥面铺的使用寿命具有重要的意义。

By analyzing technical difficulties of Maanshan Yangtze River highway bridge steel bridge deck pavement,the design requirements are determined.Considering domestic similar structures of long-span steel bridge deck pavement design index of suspension bridges,the operation conditions,engineering practice and experimental studies are compared.According to the overall structure deformation,load response characteristics,design index for steel bridge deck pavement structure layer,research achievements of scientific improvement are obtained,which can improve the performance and increase the service life of the steel bridge deck pavement structure.This work has important significance.
