| 摘 要： | 对自平衡中承式系杆拱桥的弹性稳定性能及其求解方法的研究结果表明,无论在何种荷载作用下,结构的弹性稳定安全系数都随着拱肋内倾角度的增加而增大,随着拱肋外倾角度的增大而减小.

| Abstract: | The elastic stability of self-balancing half-through tied arch bridge and the corresponding solution are studied in the paper.The result shows that under the effect of any kind of load,the elastic stability safety factor of structure will increase along with the increase of inward obliquity of arch rib,deduce along with the increase of outward obliquity of arch rib. |
