| 摘 要： | 以主跨420 m的万州长江大桥作为原型,进行了大跨度活性粉末混凝土拱桥试设计的初步分析.分析结果表明,利用活性粉末混凝土的高强度和高性能,在设计时可以采用更薄的截面形式,有效地减轻拱圈的自重,从而使主拱圈在自重作用下的内力降低,施工难度也随之降低.初步研究结果表明,活性粉末混凝土在大跨度拱桥中的应用是可能的.

| Abstract: | Taking Wanzhou Yangtze River Bridge with a main span of 420 m as prototype,a trial design of Reactive Powder Concrete long span arch bridge was carried out.Analysis results show that much thinner cross section can be adopted due to its high performance and strength,the self-weight of the rib can be reduced effectively,subsequently the internal forces caused by the self-weight and the difficulty in construction decrease notabily.Preliminary research indicates that it is possible to use Reactive Powder Concre... |
