摘要
太中线中宁黄河特大桥和永宁黄河特大桥分别采用了6-96 m双线简支钢桁结合梁和13-96 m单线简支钢桁结合梁。设计中重点对混凝土桥面板与桥面系纵横梁的结合形式、混凝土桥面板是否参与结构体系受力、高低桥面系结构形式,以及整体节点构造等设计施工中的关键性技术问题进行了深入的分析研究,确定了96 m简支钢桁结合梁合理的结构形式。
The Zhongning Huanghe River Bridge and Yongning Huanghe River Bridge on Taiyuan-Zhongwei Railway are respectively designed as 6 × 96-m span double-track simply-supported steel truss composite girders and 13 × 96-m span single-track simply-supported steel truss composite girders. In the design of the Bridges, the analysis and study are made in a deep-going way mainly from aspect of the key techniques for design and construction of the composite forms of the concrete deck slabs with longitudinal and lateral beams of the floor systems, participation of the deck slabs in load-bearing of the overall structural systems, structural forms of the unequal height floor systems and structural formation of the integral panel points. Through the analysis and study, the rational structural forms of the 96-m span simply-supported steel truss composite girders are finalized.
