| 摘 要： | 为研究斜靠式钢管混凝土拱桥的结构受力特点以及稳定特征,以一座拟建的大跨径斜靠式拱桥为例,分析了其主要结构参数(矢跨比、吊杆间距、斜拱倾角、横撑数量及位置)对结构静力性能的影响.经过结构参数对比计算分析发现:当矢跨比由1/5变化至1/6时,内力值将出现较大幅度增加;吊杆间距的增大和横撑数量的减少对斜拱受力不利;倾角的减小...

| Abstract: | In order to study the static characteristics and the stability features of concrete-filled steel tubular(CFST)double X-shape arch bridges,a 100 m span bridge to be constructed is analyzed.The influence of the key structural parameters(the ratio of rise to span,the distance between the suspenders,the rake angle of inclined arch,the number and location of transverse braces) on the internal force of the entire bridge is analyzed.The results show that: when the ratio of rise to span changes from 1/5 to 1/6,the ... |
