Mechanical responses of underground carriageway structures due to construction of metro tunnels beneath the existing structure: A case study
• A simulation of the construction process of a shield tunnel and a shallow tunnel traversing beneath an existing underground carriageway is carried out. • The torsional deformation features of the existing structure are studied. • The mechanism and influence pattern of the “shield effect” of the existing structure on stratum subsidence are examined.
