南照淮河公路大桥主桥箱梁逆作法拆除分析

Analysis on reverse dismantling of major Huaihe highway bridge box girder in Nanzhao

通过对南照淮河公路大桥主桥箱梁逆作法拆除全过程的有限元分析,验证当前上部结构安全性和逆作法拆除施工方案的合理性,对各施工阶段主梁内力与变形展开分析,保证了桥梁拆除施工的安全性。

Through finite element analysis for the whole reverse dismantling process of major Huaihe highway bridge box girder in Nanzhao,the paper testifies the current upper structure security and the rationality of reverse dismantling construction scheme,analyzes internal major beam and deformation at various construction phases,and finally guarantees the bridge dismantling construction safety.
