摘　　要：为提高双向倾斜索塔在施工过程中的安全性及成塔状态下满足应力和线形的要求。该文以柴埠溪大桥西侧索塔为背景,介绍了索塔施工过程中的临时拉杆和临时横撑的布置、施工力的计算、临时结构的设计等内容。施工过程中产生的塔柱应力,成塔状态下的位移和应力均满足要求。主动力施加时温度对其影响以及临时拉杆和临时横撑与温度的修正关系。临时结构的应力和稳定性满足规范要求。可为今后的同类型斜拉桥索塔塔柱施工提供参考。In order to improve the safety of two-way inclined cable tower during construction and meet the requirements of stress and line shape in the tower state.Taking the tower on the west side of Chaibuxi bridge as the background,this paper introduces the layout of temporary cable and temporary braces,the calculation of construction force and the design of temporary structures during the construction of the tower.The stress of the tower column during construction and the displacement and stress when the tower is completed meet the requirements.The effect of temperature on the main power when it is applied and the correction relationship between the temporary tie rod and the temporary cross brace and the temperature.The stress and stability of the temporary structure meet the requirements of the specification.It can provide a reference for the construction of similar cable-stayed bridges in the future.
