摘要:
A tunnel face failure is simulated by pulling out a tunnel model set in a model ground. The ground is then investigated by X-ray computed tomography (CT) scanner in order to not only visualize the failure zone in three-dimension but also evaluate mechanism of the face failure. Here, the effect of overburden and pull-out length on the scale of failure zone is evaluated quantitatively. Finally, it is concluded that the mechanism of face failure can be investigated visually in three-dimension by the proposed test method. And the quantitative discussion on the face failure mechanism is well performed.
