摘要
以肥西路门式刚构桥为例,阐述该桥在设计中的技术特点和难点,分析不同的结构体系和立柱材料对结构内力的影响。通过优化主梁断面布置形式,注重各关键节点的设计,保证该桥受力合理,施工及运营安全可靠。
Combined with the case of Feixi Rd. portal type rigid frame bridge, the technical features and difficulties of the bridge design are presented in this paper. It analyses effects of different structure systems and column materials on internal force of the bridge structure. By optimizing the layout form of the main beam section and paying attention to the designs of the key nodes, it ensures the bridge reasonable stress, safe construction and reliable operation.
