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

It is proved that the main affecting factors include: equivalent pile length, bending stiffness of abutment, ratio of width to span, distance of webs, etc.
整体式桥台的等代桩长、桥台纵向抗弯刚度、宽跨比及箱梁肋板间距等,是影响该类桥梁剪滞系数的主要因素。

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.
