摘　　要：钢拱塔斜拉桥是一种新颖的桥梁结构形式,常用于城市景观桥梁,目前对其施工工艺研究的资料较少。本文主要介绍应用塔架转体方案完成钢拱塔斜拉桥竖转施工的力学分析方法,以及方案应用的适合条件,并以某大桥钢拱塔竖向转体为例进行了分析,为今后类似桥梁施工提供借鉴。Cable-stayed bridge with steel arch tower is a new kind of bridge form, mainly applied in urban land- scape bridge, but the information of researching its construction technology is not enough. Taken analy sis about vertical swivel of one bridge with steel arch tower as an example, mechanical analysis method and applicable condition about the vertical swivel of such bridges using the method of promotion of tower frame were introduced, which could be refered by similar project.
