文章以特大跨径悬索桥主缆架设施工为背景(主缆采用PPWS法进行架设),文中针对悬索桥主缆索股数量多、重量大、长距离牵引施工的技术难题,结合“四新”技术,进行主缆索股大吨位、超长距离牵引新技术的研究;通过国内外悬索桥施工采用的牵引技术进行综合分析和比较研究,结合工程实际,深入研究了双线往复式门架拽拉器式牵引系统,取得了一系列富于实用价值的研究成果,对今后大跨径悬索桥主缆架设施工有很好的借鉴作用。
In this paper, based on the construction of the main cable truss of the super-long span suspension bridge (the main cable is erected by PPWS method), the paper discusses the technical problems of the construction of the main cable of the suspension bridge with large number, heavy weight and long distance, , The main cable rope unit large tonnage, long distance traction new technology research; through the domestic and foreign suspension bridge construction using the traction technology to conduct a comprehensive analysis and comparative study, combined with engineering practice, in-depth study of double-reciprocating gantry dragger type Traction system, has made a series of rich practical results of research, the future of large-span suspension bridge main cable laying facilities have a good reference.
