Abstract

Shield jamming is an important engineering geological problem that restricts safe, efficient construction of double-shield tunnels by tunnel boring machines (TBMs). Many factors influence shield jamming with numerical simulations needed to analyze the influences of these many factors. This study used numerical simulations of the tunneling process of a double shield TBM. The simulations use the creep model based on internal variable thermodynamics theory to simulate the time-dependent deformation of the surrounding rock and the interactions between the surrounding rock and the shield. The simulations were used to analyze the influence of two shield jamming control factors, the TBM advance rate and the overcut, for a highway tunnel. The results show that increasing the advance rate somewhat reduces the contact force and the shield jamming risk. The overcut has a larger effect on the contact force. Careful use of these two shield jamming control measures is more important for tunnel construction with high ground stresses and soft rock conditions. These results provide a reference for shield jamming risk analyses and optimizing the TBM parameters such as the advance rate and the overcut.
