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。
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.
对于矢跨比较小的坦拱，矢高与截面回转半径的比值将决定拱的屈曲形式。
Secondary buckling mode of shallow arches depended on the ratio of rise to gyration radius.
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。
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.
