| Abstract: | West fourth ring road buried culvert was gravel(scree) strata in Beijing branch of the middle line of South-to-North Water Transfer Project, using New Austrian Tunnelling Method(NATM) by Shallow-buried. There are many pipelines cross in buried culvert project ,which went through west fourth ring subway pile foundation, as a result of NATM by Shallow-buried existing some difficulties.So carry through the construction technology of typical sect of NATM by Shallow-buried summary on west fourth ring road buried culvert of Beijing branch of the middle line of South-to-North Water Transfer Project, which would offer reference for future similar projects. |
