摘要
采用顶推法实施在不中断交通的条件下拆除跨越高速公路钢筋混凝土连续箱梁桥,对主梁的支撑形式进行了根据顶推施工的需求改造,并分析研究了顶推施工过程及顶升桥梁更换支座施工中主梁、桥墩的结构受力,结果表明方案安全、可行。
dismantle the reinforced concrete continuous box girder bridge cross highway without in- terrupting traffic conditions by incremental launching method, change the form of the support of bridge, Analysis the internal forces and displacement of the girder and pier under the Incremental Launching the construction process and the lifting bridge replacement bearing construction, The results show that the program is safe and feasible.
