摘　　要：以高新二路跨外环桥梁施工为例,介绍了倾斜独塔斜拉桥钢塔竖转施工方法。竖转施工主要步骤为:钢塔拼装、D0节段安装、竖转系统安装、钢塔试竖转、正式竖转、体系转换。该桥钢塔竖转的成功实施可为同类型桥梁竖转施工提供参考。Taking the construction of the Second High-Tech Road Bridge Over the Outer Ring as an example,this paper introduces the construction method of steel tower vertical rotation of inclined single tower cable-stayed bridge. The main steps of vertical rotation construction are: steel tower assembly,D0 section installation,vertical rotation system installation,steel tower trial vertical rotation,formal vertical rotation and system transformation. The successful implementation of the vertical rotation of the steel tower of the bridge can provide reference for the vertical rotation construction of the same type of bridge.
