摘要
重庆市鹅公岩轨道专用桥位于既有鹅公岩大桥上游70 m,主桥采用自锚式悬索桥结构,主梁为混合梁,中跨及边跨为钢箱梁,锚跨及锚固段采用混凝土箱梁。设计对超大跨自锚式悬索桥的刚度标准、稳定性、关键节点的受力进行分析及试验,并对“先斜拉后悬索”的体系转换工法等进行研究。重点介绍该桥科研项目的规划和实施情况。
Chongqing Egongyan special bridge for track is located 70 m upstream of the existing Egongyan Bridge.The main bridge adopts selfanchored suspension bridge structure,the main beam is composite beam,the middle span&side span are steel box girder,and the anchor span&anchorage section are concrete box girder.The rigidity standard,stability&stress of key nodes of the super-long-span self-anchored suspension bridge are analyzed&tested in the design,and the system conversion method of cable-stayed firstly and then suspension is studied.This paper focuses on the planning&implementation of the bridge scientific research project.
