Review and Prospects on Constructing Technologies of Metro Tunnels Using Shield Tunnelling Method

With the rapid development of metros in China, shield Tunnelling method, which is considered as a safe, environmental and quick construction method, has been widely applied in metro tunnel construction, and gradually become a hotspot in the world. In this paper, through review of the state-of-the-art of metro shield Tunnelling technologies and their latest new trends, technical problems in metro tunnel construction by shield Tunnelling method were discussed, and the related technology development and research progress in metro shield Tunnelling construction in recent years were summarized, including shield equipment manufacturing technology and shield selection technology, the environmental impact and control measures during shield construction, the behavior of shield tunnel lining structure under complex conditions, deterioration characteristics and durability of shield tunnel lining structure, and the impact and evaluation of disasters or accidents. Moreover, the technology development direction and research trends of metro shield tunnel in the near future are discussed in terms of manufacture and application of the special-face shields, constructing metro stations by enlarging shield tunnel, impact and assessment of disasters or accidents, system construction for lining structure safety assessment, repair and maintenance, etc.
