Abstract

The rock tunnel boring machine (TBM) is a hybrid system that uses the TBM to excavate a tunnel whereas the ground is supported by a ring beam, wire mesh, rock bolt, and shotcrete; having an appropriate tunnel support system during tunnel excavation is very important with this method. From this point of view, a pressurized ring beam might be one way to improve tunnel stability. To verify the effect of the pressurized ring beam, a numerical study with a three-dimensional finite element method model and an experimental study using the trapdoor test were conducted. The results of these studies showed that the higher the force applied to the ring beam, the less tunnel convergence occurs.
