摘要
润扬长江公路大桥采用正交异性钢箱梁结构,桥面铺装层在国内首次采用“浇注式沥青混合料+环氧沥青混凝土”的新型复合铺装结构。通过对润扬大桥试验桥的钢板表面应变测试结果与理论计算值之间的差异进行比较,检验试验桥钢桥面铺装结构体系设计理论和计算方法的正确性,为润扬长江公路大桥钢桥面铺装结构体系的设计积累理论基础。
The orthotropic steel - deck structure is adopted in the Runyang Yangtze River Bridge. The new composite structure of ' Guss asphalt + epoxy asphalt concrete' is first used as pavement meterial in China. The difference of strain between testing results and computing results of the Runyang Testing Bridge is compared, and the theory and computing method of steel deck bridge surface system is proved to be correct. The researches provide the theoretic basis for the design of deck surface system of the Runyang Yangtze River Bridge.
