| Abstract: | The main bridge of Yinchuan Binhe Huanghe River Bridge is a three-pylon double-plane composite girder self-anchorage suspension bridge.Its span layout is 88 m+218 m+218 m+88 m.In order to safely and efficiently realize the system transition,it is required to select the reasonable suspender tension scheme.Various control factors should be comprehensively considered in the construction process.Therefore,the suspender tension scheme of three-pylon self-anchorage suspension bridge is studied.By calculation and analysis,the selected system transition scheme can meet the technical standards of various construction procedures in the construction process. |
