Abstract:

As for the occurrences of safety quality accidents like ground settlement and gushing water and gushing sand caused by the failure of timely monitoring of over-excavation and geological mutation due to the geological conditions and equipment limitations over the construction of shield tunnel works, this thesis puts forward the application of radial hole on the shield body of a shield machine-a simple and operable supporting construction method, and its application practices, which provides a new way of thinking to the construction of shield tunnel works.

Key words: shield, radial hole, application
