Description

Technical Field

[0002] Currently, the most common combination of cut-and-open station construction and shield-bored tunneling is used in subway design. Due to numerous factors, including existing buildings, dense underground pipelines, and heavy surface traffic, the use of the tunneling method is becoming increasingly widespread in underground structures.
