| 摘 要： | 悬索桥结构施工过程中难度最大、技术含量最高、最难以控制的是缆索系统的安装,对于空间索面的缆索系统而言,不同的吊索安装程序、张拉顺序及张拉力值均将对主缆的空间位置产生重大的影响,并直接影响到施工工期和成桥时的状态.通过单塔空间索面自锚式悬索桥--天津富民桥缆索系统安装与体系转换的实际施工控制过程,验证了所采用的施工控制方法与控制计算结果的科学性、合理性,对缆索系统的安装施工起到了很好的指导作用.

| Abstract: | In the construction process of suspension bridge structure,the part of the work that has the greatest difficulty,richest technical content and that is the most difficult to control is the installation of cable system.For a suspension bridge with the spatial cable plane cable system,the different installation procedures,tensioning steps and tensile force values of the hangers of the bridge will have significant influence on the spatial positions of the main cables and will directly affect the working time sc... |
