摘　　要：随着数控技术越来越成熟,大跨斜拉桥桥塔采用转体施工是未来的发展的趋势,设计师需要从初定的转体方案中,精准分辨可能对永久构建产生影响的关键点。借助实际桥塔转体案例,总结和归纳斜拉桥塔转体过程中需要注意的关键点。With the more and more mature CNC technology,the rotating construction of large-span cablestayed bridge tower is the future development trend. Designers need to accurately distinguish the key points that may have an impact on the permanent construction from the initial rotation scheme.With the help of the actual case of the transfer of the bridge tower,this paper.
