中文摘要：

等截面、无预应力筋的波形钢腹板曲线连续箱梁桥由于建造较少,其合理的边中跨比例关系尚未研究。本文通过力法对三跨等截面连续波形钢腹板曲线箱梁桥在恒载和活载作用下,不同边中跨比值对中跨与边跨最大弯矩的影响进行参数分析,得到等截面、无预应力筋的波形钢腹板连续箱梁桥的合理边中跨比值,并针对不同梁高的波形钢腹板曲线箱梁给出合理跨径,为今后此类桥型的设计提供参考。

英文摘要：

Rational span arrangement of curved reinforced box-girder bridge with corrugated steel webs is stiff uncertain for its shortage of design and construction. In this paper, the influence of the ratio of side span to middle spanon maximum bending moments of side span and middle span was explored by using force method. Rational ratio of side span to middle span of curved reinforced box-girder bridge with corrugated steel webs and rational span of curved reinforced box -girder bridge with corrugated steel webs of different height of cross section were obtained, which provided reference for bridge design of this kind.
