近年来,悬索桥施工工艺方法及选材发展迅速,却也带来了一系列问题。其中,由于其桥塔的逐渐高耸化,塔柱截面的逐渐薄壁化以及新型材料的使用,导致桥塔刚度下降,从而不可避免地影响到了桥塔结构的稳定性。本文借助对某悬索桥桥塔的分析,讨论了影响悬索桥桥塔稳定性的几个因素,得出了若干因素对桥塔结构稳定性的影响机理以及影响程度。 In recent years, the suspension bridge construction methods and selection of materials developed rapidly, but it also brought a series of problems. Among them, due to its towering towering towering gradually taper column section thinning and the use of new materials, leading to the stiffness of the bridge tower, which will inevitably affect the stability of the bridge tower structure. In this paper, by analyzing the bridge tower of a suspension bridge, several factors that affect the stability of the bridge tower are discussed. The influence mechanism of several factors on the stability of the bridge tower is obtained.
