隧道在我国工程建造中经常出现,隧道支护变形也时常发生,如何安全拆换变形支护是关系到隧道能否顺利贯通的关键。本文以实例分析,如何对隧道支护变形进行拆除及处理,保证隧道正常施工,提出了一些施工技术和方法,希望有所帮助。 The tunnels often appear in the construction of our country. The deformation of the tunnel support also occurs frequently. How to safely replace the deformation support is the key to the smooth tunneling. In this paper, an example is given to analyze how to dismantle and treat the deformation of the tunnel support and ensure the normal construction of the tunnel. Some construction techniques and methods are proposed, hoping to be helpful.
