刚性悬索加劲刚桁架梁桥施工技术

Construction Technology of Rigid Suspension Stiffened Rigid Truss Beam Bridge

文章以大桥工程项目为例,首先对比分析了施工方案,以及进行钢桁梁施工设计,然后从桁梁安装、刚性悬索安装以及合龙段安装方面重点研究了刚性悬索加劲钢桁梁施工技术。实践表明,此大桥项目刚性悬索加劲钢桁架梁采用的施工技术合理、可行,切实保证了大桥项目施工质量及安全,也为类似项目施工提供了参考与借鉴。

Taking the bridge project as an example,this paper first compares and analyzes the construction scheme and the construction design of steel truss beam,and then focuses on the construction technology of rigid suspension stiffened steel truss beam from the aspects of truss beam installation,rigid suspension cable installation and closure section installation.The practice shows that the construction technology adopted for the rigid suspension stiffened steel truss beam of the bridge project is reasonable and feasible,which not only ensures the construction quality and safety of the bridge project,but also provides a reference for the construction of similar projects.
