曲面索塔结构线型控制施工技术

Construction Technology for Linetype Control of Curved Cable Tower Structure

重庆东水门长江大桥索塔设计为天梭外形,形状复杂,尺寸变化大。通过建立实体模型和杆系模型,对该桥施工过程中的岔区应力、牛腿应力、塔柱应力进行分析计算,并提出控制措施,以确保结构线型满足设计要求。

Cable tower of Chongqing Dongshuimen Yangtze River Bridge is designed in Tersedo appearance with complicated shape and large change of size. By establishing entity model and bar system model, this paper analyzes and calculates bifurcation area stress, bracket stress and tower column stress, and proposes control measures to ensure structural linetype satisfies design requirements.
