1) long span half-through arch bridge
大跨度中承式拱桥
1.
Be differ from the long span cable-stayed bridges and suspension bridges, the long span half-through arch bridges belong to 3D structure.
大跨度中承式拱桥属于柔性结构,在风振作用下很容易发生静风失稳、抖振和涡激振动等风致响应。
3) Long-span top-bear arch bridge
大跨度上承式拱桥
6) long-span arch bridge
大跨度拱桥
1.
Calculation of the cable-stayed force and Pre-camer is the difficulty and key problem in assembling a long-span arch bridge by using construction of non-bracket cable-stayed suspension.
扣索索力确定和标高预抬量计算是大跨度拱桥在采用无支架缆索吊装施工过程中的难点和核心问题,本文在原有的连续体弹性-刚性支承法的基础上,提出了改进的弹性-刚性支承法:即当前施工节段处的扣索模拟为刚性支承,对已施工节段的扣索模拟弹性结构,节段之间的连接考虑为转动弹簧。

The elastic-rigidity supporting method is presented for determination of the buckling cable force and precamber, which is the difficult point as well as the key problem in assembling a long-span arch bridge.
扣索索力和预抬量是大跨度拱桥的拱圈拼装过程中的难点和核心问题。
3.
As known, the effect of traveling wave is noticeable on seismic response of the long-span arch bridge.
拱桥在我国是一种常见的桥梁结构型式，对于大跨度拱桥，地震动的行波效应不可忽视。
