斜拉桥主塔施工方法

摘要

结合高低塔型斜拉桥主塔的施工实践，介绍了高低塔型斜拉桥主塔总体施工工艺，论述了主要施工设备选型与布置方式，主要对塔柱、上下横梁、塔柱及横梁预应力钢筋张拉等施工过程中的要点进行了研究，为今后类似工程施工积累了经验。%Combining with the construction practice of high and low tower cable-stayed bridge main tower,this paper introduced the overall con-struction technology of high and low tower cable-stayed bridge main tower,discussed the main construction equipment selection and arrangement, mainly researched the key points of tower pillar,upper and lower beam,tower pillar and beam pre-stressed reinforcement tensioning and other construction process,accumulated experience for future similar engineering construction.
