摘　　要：以某在建主跨110 m异型桥塔斜拉桥为例,基于钢桥塔索塔锚固区构造的合理简化,建立有限元模型,分析了不同工况下钢桥塔的受力和变形,给出需要改进的设计要点以及在设计和施工中应注意的问题,得到了该锚固区的应力大小和分布规律。Taking some building main span 110 m irregular bridge tower cable-stayed beidge as example, based on the reasonable simplification of steel bridge tasso tower anchor-range configuration, the finite element model was built, the stress and deformation of steel bridge tower at different working conditions were analyzed, the design points need to reform and problems need to attention in design and construction were given, and the magnitude of stress and distribution law of this anchor-range were got.

关 键 词：钢桥塔 钢锚箱 应力 变形
