银西高铁银川机场黄河特大桥主桥总体设计
Overall Design of Main Bridge of Yinchuan Airport Yellow River Bridge on Yinchuan-Xi'an High-speed Railway
摘要
Abstract
The simple steel truss girder with span of 96 m and equal span of 168 m continuous steel girder flexible arch structures are used in the main bridge of Yinchuan Airport Yellow River Bridge on Yinchuan to Xi'an High Speed Railway.The structure of the continuous steel truss with flexible arch employed in the main bridge is novel in form and technically complex.The main bridge spans over the Yellow River.The seismic intensity of the bridge site is high, the icing is severe in winter and the available construction period is short.Due to the special construction conditions of this bridge, it is difficult to design and construct the bridge.In order to demonstrate the characteristics of the design and construction of the main bridge, the selection of the scheme of the main bridge, the overall layout, the installation of the bridge deck, the design of the boom and the basic settings are introduced.The main calculation results and the boom test results are presented.The key technologies used in the seismic design, support design, and bolt fall prevention design of this bridge are addressed.Finally, the innovative construction scheme adopted for the main bridge is illustrated.关键词
