摘　　要：斜拉拱桥是一种新型的拱桥结构形式。本文对斜拉拱桥与普通拱桥平面模型的弹性稳定性进行了对比分析,计算分析了斜拉拱在不同矢跨比、边界条件、荷载工况下的面内弹性稳定性,并讨论了斜拉索张拉参数(在拱上张拉位置、斜拉索倾角)对斜拉拱桥平面内弹性稳定性的影响。The cable-stayed arch bridge is a new kind of arch structural bridge. The comparative analysis of the planar elasticity stability is made between cable-stayed arch bridge and normal arch bridge. Meanwhile,the planar elasticity stability of cable-stayed arch is calculates and analyzed under the different working conditions of rise span ratio, boundary condition and loading. The influence of tension parameters(tension location on arch and inclination of stayed cable) of stayed cable on the planar elasticity stability of cable-stayed arch bridge is discussed.
