These are prestress in cables, sag of cables, rise of arches, the vertical flexible stiffness of arches and the axial stiffness ratio between the cable and the arch.

这些参数为索预应力、索垂度、拱矢高、拱竖向抗弯刚度以及索和拱的轴向刚度比。

Onthis foundation, the best range of rise-span ratio of arch bridge which reachesits limitation span is discussed.

并以此为基础，就极限跨径下拱桥的最佳矢跨比范围进行讨论。

For a secondary bifurcation buckling load, the limit load carried capacity of the arch of 0.1 rise-span ratio is the biggest one under a full span load distribution.

全跨均布荷载作用下，矢跨比0.1的拱极值点屈曲和二次分岔屈曲极限承载力均大于其他拱。

Those who wish to see the arch rise again want it to be of the same scale as the original.
