作者董云鹏（2019）在《双塔钢箱桁梁斜拉桥斜拉索安装关键技术》一文中研究指出：研究目的:商合杭铁路裕溪河特大桥（60+120+324+120+60） m双塔钢箱桁梁斜拉桥是目前我国时速350 km高速铁路最大跨度的钢箱桁梁斜拉桥,且主梁结构形式为国内高铁首次使用[1]。该桥斜拉索安装分两种工况:边跨钢梁顶推到位、落梁后,一次性挂设前7对斜拉索;跨中梁段悬拼架设,每架设一个节段,挂设一对斜拉索,最后进行全桥调索。斜拉索施工质量要求高,本文针对斜拉索安装重难点从展索设施、运输存放、张拉等方面进行斜拉索安装关键技术的研究[2]。研究结论:（1）斜拉索施工中应针对结构施工的特点,结合实际条件进行施工方案确定,本工程参考现场实际条件,经过研究决定提出桥下存放、汽车吊提升展索、软硬牵引相结合的斜拉索总体安装方法;（2）斜拉索采用汽车吊提升锚头,在塔端锚头处安装组合张拉杆及抱箍,连接塔吊吊钩,配合塔吊进行斜拉索牵引展索的施工方法能够提高施工安全系数,提高效率;（3）采用塔柱内腔增加由撑脚、螺帽辅助布设的卷扬机进行牵引施工,能够解决塔内空间小不利于斜拉索牵引施工的难题;（4）斜拉索施工中在塔端增加调位夹具,地面由两台塔吊进行两点起吊施工的方法利于塔端牵引安装;（5）本研究成果适用于大部分斜拉桥的斜拉索施工,尤其适用于作业空间狭小的斜拉索施工。
