结合鄂东长江公路大桥初步设计阶段推荐方案所提出的主梁钢混结合段位置设置的3种方案,通过其受力性能差异、施工难易程度、工期长短、造价高低以及养护难易程度等方面的比较,推荐主梁钢混结合段位置设置的最佳方案。 According to the three schemes proposed by the recommended scheme of the main beam and steel mixing section proposed in the preliminary design stage of the Yangtze River Highway Bridge in East Hubei, through the difference of its mechanical performance, the difficulty of construction, the length of construction period, the cost, the ease of maintenance and so on In terms of comparison, it is recommended that the optimal solution be set for the location of the main girder steel and concrete mixing section.
