望(江)东(至)长江公路大桥是安徽省过江通道规划中的一座重要跨江桥梁,主跨为638m,主梁采用组合梁结构,如何确定合理组合梁结构形式是设计的关键问题。本文结合当地水文、风速、温差等自然条件出发,在满足使用功能,并适度超前的设计原则基础上,提出该桥设计的合理组合梁结构方案。 Wangjiang River (to) Yangtze River Bridge is an important cross-river bridge in the planning of overpass passage in Anhui Province. The main span is 638m, and the main beam adopts the composite beam structure. How to determine the rational composite beam structure is the key issue in design . Based on the natural conditions of local hydrology, wind speed, temperature difference and so on, based on the design principle of meeting the using function and keeping a modest degree of advancement, this paper proposes a reasonable composite beam structure scheme of the bridge design.
