96m钢桁梁邻近高铁带纵坡水平横移技术

Horizontal Transverse Displacement Technology of 96m Steel Truss Beam Adjacent to High Speed Rail

带坡度横移施工技术较为新颖,尤其是邻近高铁施工难度和风险较大。以南京市宁和城际跨越板桥河为例,对邻近既有高铁的钢桁梁施工难度进行分析,提出了钢桁梁带纵向坡度横移的技术方案,并对其具体措施进行了详细的阐述。最终通过过程中的施工监测结果对方案可行性进行了验证,对后续类似工程具有很好的借鉴意义。

The construction technology of slope moving is relatively new, especially the construction of adjacent high-speed rail is more difficult and risky. This paper takes Nanjing city Ning and intercity bridge across the river as an example, close to existing high iron steel truss construction difficulty analysis, put forward the technical scheme for steel truss girder with longitudinal slope sliding,and the concrete measures are discussed in detail. Finally, the feasibility of the scheme is verified by the results of the construction monitoring, which has a good reference for similar projects.
