摘　　要：针对高速铁路桥梁水平转体扣背索施工技术的应用要点,结合新建成贵铁路西溪河大桥实际情况,立足转体体系和扣背索系统的工艺特征,分析了扣背索施工技术在成贵铁路西溪河大桥水平转体工程项目中的应用。结果表明,高速铁路桥梁水平转体工程项目结构复杂、施工难度大、施工条件有限,采取扣背索施工技术可为水平转体施工营造良好的环境,保证后续各道工序能够安全、高效地完成,为类似工程提供参考借鉴。Aiming at the application key points of the horizontal swivel buckled cable construction technology of high-speed railway bridges, the application of buckled cable construction technology in the horizontal swivel project of Chengdu-Guiyang railway bridge across Xixi River is analyzed based on the actual situation of the newly-built Xixi River Bridge and the technological characteristics of the swivel system and the buckled back cable system.The results show that the high-speed railway bridge horizontal swivel project has complex structure, great difficulty in construction and limited construction conditions. The adoption of the buckle-back cable construction technology can create a good environment for the horizontal swivel construction and ensure that the subsequent processes can be completed safely and efficiently, which provides reference for similar projects.
