针对该桥自身的特点，对拱肋矢跨比，轴线方程，截面的几何尺寸等主要技术参数做了探讨。
In connection with its self properties, we make an inquiry into the major parameters, such as ratio of height and span, equation of arch axis, geometry size of section and so on.
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.
但由于拱体的横向尺寸总是有限的，往往使得大跨径拱桥的宽跨比很小。
However, the width of an arch has a limitation which leads to the long span archs lateral stability lower because of its small ratio of width and span.
