Abstract

Inthispaper,theconstructionmethodofthemulti-archtunnelgroupisdiscussedbyusinganengineeringexampleofMetroLine3.Intheconstructionofthesubway,theconstructiontechniqueofchangingamulti-archtunnelintoasingle-holetunnelwasfirstproposed.Thetechnicalsolutionsofthesingle-middlewallandtheseparatedmiddle-wallstructurewerecomparedandselectedtomeettherequirementsofstructuralsafety,constructionsafety,andeconomicefficiency.Goodtechnicalsolutionscanprovidereferenceandreferenceforthedesignandconstructionofsimilarprojectsinthefuture.
