Abstract:

A large scale shield machine boring in sandcobble ground is jammed and a shaft is constructed ahead of the shield machine for the purpose of shield releasing. The design and construction of the shaft, the boring of the released shield and the backfilling construction of the shaft are presented in the paper, which can provide reference for similar projects in the future.

Key words: shield rehabilitation shaft  , jammed shield releasing complex environment design  , construction
