斜拉桥大曲率+多曲率人字形主塔施工技术研究

Research on Construction Technology of Large Curvature + Multi Curvature Herringbone Main Tower of Cable Stayed Bridge

开源桥主塔塔造型独特,正面设计为人字形,侧面呈Y字形,由于主塔正面、侧面设计为曲线造型,故两侧塔柱沿高度方向均为渐变截面,自塔底至塔顶每个截面尺寸均不相同,造成极大施工难度,其中下塔柱0~5号节段造型尤为独特,决定各节段模板组合、加固方法又各不相同,本文着重对主塔各节段施工方法及施工要点进行论述。

The main tower bridge open source unique,positive for human side shape,the shape of Y,the main tower of the front and side design for curve shape,so the tower on both sides along the height direction are tapered from the bottom to the top of the tower,each section sizes are not the same,causing great difficulty in construction,which under the tower No. 0 ~ 5 other segment is particularly unique,decided each segment template combination,reinforcement method is also different. This paper discusses the construction method of each section of main tower and main points of construction.
