Highlights

• 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.
