The influence to stress of skew arch bridge was studied by changing the abutment torsional stiffness and width-span ratio.

通过改变桥台抗扭刚度和宽跨比，研究对斜交拱桥受力的影响。

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.

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。

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.

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。
