文一路地下通道工程西溪河桥既有桥梁拆除安全施工技术

Application of Safety Construction Technology to Dismantling the Existing Bridges--Dismantling of Xixi River Bridge of Wenyi Road Underground Passage Project

在一些城市建设中,现有桥梁会对道路拓宽、基坑开挖或盾构隧道施工产生阻碍,施工过程中需对其进行拆复建。文章结合文一路地下通道中的西溪河桥梁拆复建工程,对钢箱梁、拱桥拆除的施工技术及施工注意事项进行了简要的介绍,为后续工程起到一定的借鉴作用。

In urban construction, the existing bridges sometimes hinder the road widening, excavation and tunnel shield construction. Therefore, in construction, the existing bridges need to be dismantled and rebuilt. This paper briefly introduces the construction technology and notes of dismantling and rebuilding Xixi River Bridge of Wenyi Road Underground Passage Project including steel box beam and arch bridge dismantling, which would be a helpful reference to following projects.
