摘要
为了优选合理的城市道路高架桥上部结构梁,文中从造价角度对比分析跨径对不同高架桥上部结构形式的影响.结果表明,跨径每增加1m,预制小箱梁单位面积造价提升 73.3 元,预制T梁工程造价提升 67.3 元,大跨度桥梁中钢箱梁工程造价增加 70.7元,大跨度桥梁中钢混连续梁工程造价增加62.7 元.综合造价、施工周期等因素,推荐预制T梁作为高架桥标准跨的上部结构,钢混连续梁钢结构为大跨度桥梁上部结构形式.
Abstract
In order to select the reasonable superstructure beam of urban road viaduct,this paper analyzes the influence of span on different su-perstructure types of viaduct from the perspective of cost.The results show that for every 1 m,the cost of prefabricated small box girder increa-ses by 73.3 yuan,the cost of precast T-beam increases by 67.3 yuan.The cost of steel box girder increases by 70.7 yuan,62.7 yuan,and the cost of steel concrete continuous girder of large-span bridge increases by 62.7 yuan,the superstructure of viaduct standard span is recom-mended;steel concrete continuous beam is the superstructure of large-span bridge.
