| 摘 要： | 针对不同类型的概化河道和天然河道地形,结合桥墩布置方式和边坡系数的不同组合,对桥梁工程阻水比与河道水位变化之间的内在联系进行初步探讨和研究.结果表明:桥梁工程阻水比与河道水位(f/F-Z)之间的变化关系由桥墩阻水面积增幅△f与河道过流面积增幅△f两者的比值随水位Z升高时的整体变化趋势决定,而△f与△f何者占优同桥墩布置方式及边坡系数两者的综合影响密切相关.位于主河槽内的桥墩权重比例占优,f/F-Z呈反比关系;位于滩地的桥墩权重比例占优,f/F-Z呈正比关系;两者权重比例相当则分段呈单调递增或递减趋势.相同桥墩布置方式下,边坡越缓,f/F-Z越趋于反比;反之,越趋于正比.

| Abstract: | Aiming at different kinds of man-made or natural watercourse,and considering the various arrangement between bridge piers distribution and different slope of the river bank,the inner relationship between water resistance ratio(f/F) and variation of water level(Z) in bridge engineering is discussed in this paper.The results show that the various relationship between f/F and Z in bridge engineering is determined by the whole variational trend of ratio between the resistance area augmentation of the bridge pie... |
