Abstract
The main bridge of Mogu River No.2 bridge is (97 +2 × 180 +97) m composite structure of continuous rigid frame with truss on Yinchuan-Xi'an high-speed railway,and it has the largest span of its kind in China.In this paper,the design method of this bridge is described in detail,the scheme selection and controlling factors of the main bridge are analyzed,and the difficulties in the selection of length and height of the reinforced steel truss of the composite girder,the design of connection node,the creep deformation control and the vertical deck displacement due to temperature difference between girder and truss are discussed,which lays the foundation for the application of the structure in bridges of high-speed railway.关键词
