针对现阶段大跨度桥梁快速施工需要,结合桃花峪黄河大桥主桥施工过程中采用的多项自锚式悬索桥同步施工技术的研究与施工实际情况,重点介绍了自锚式悬索桥在主梁安装与主塔同步施工、主塔上横梁与主索鞍安装同步施工和中跨猫道架设与主梁安装同步施工技术,该技术的运用对缩短自锚式悬索桥施工工期具有较好的指导意义。
Aiming at the needs of rapid construction of long-span bridges at this stage, the research and construction of a number of self-anchored suspension bridges used in the construction process of the main bridge of Taoyuyu Yellow River Bridge are introduced. The installation and application of self-anchored suspension bridges The main tower synchronization construction, the main tower beam and the main saddle installation of synchronous construction and installation of mid-span catwalk and girder simultaneous construction technology, the use of this technology to shorten the construction period of self-anchored suspension bridge has a good guiding significance.
