Formation Mechanism and Prediction of Shield Gripping in Shielded TBM
This paper mainly focuses on the problem of"shield gripping"that occurs during the tunnel excavation process using the shielded Tunnel Boring Machine(TBM).It analyzes the generation mechanism of shield gripping caused by factors such as rock deformation,and proposes a prediction method and risk assessment approach for shield gripping and jamming in the preliminary investigation and design stages.
