摘要
分析大跨度斜拉桥临时墩的设置机理,调研国内外大跨度斜拉桥临时墩设置情况,介绍上海长江大桥主桥结构特点和临时墩的平面设置及结构设计原则,通过对关键受力工况进行仿真分析、研究,首次提出并成功应用了承插式同步液压提升临时墩的施工技术思路。
In this paper, the mechanisms of temporary pier arrangement for long span cablestayed bridges are analyzed, the situations of the pier arrangement for the cable-stayed bridges at home and abroad are investigated and the structural features of the main bridge of Shanghai Changjiang River Bridge, the plan arrangement and structural design principles of the temporary piers for the Bridge are introduced. On the basis of the simulation analysis and research of the key load cases, the considerations of construction techniques for the inserted and synchronous hy- draulically-lifted temporary piers are put forward and successfully applied for the first time.
