| 摘 要： | 将组合结构应用到拱桥中,用平钢腹板来代替混凝土腹板可以达到减轻桥梁自重的目的。以重庆武隆石桥水库大桥为原型,进行平钢腹板混凝土新型拱桥的试设计,并与混凝土腹板拱桥、波形钢腹板混凝土拱桥在受力及用料方面进行了对比。结果表明:采用钢腹板设计的混凝土拱桥减轻了自重,减小了拱桥推力和拱肋轴力,缩短了全桥工程量。

| Abstract: | Composite structure was applied to the arch bridge.Taking Chongqing Wulong shiqiao Reservoir Bridge as the prototype,it carried out flat steel webs concrete arch bridge trial design,and contrasted the flat steel webs concrete arch bridge with the corrugated steel webs concrete arch bridge in the respects of force and materials.The results show that steel webs arch bridge reduces its own weight,the push force,the axial force of steel webs and the quantity of the whole bridge. |
