The surrounding rock of underground tunnel often fails under a variety of influencing factors. In this study, the influences of four factors (the arch height, initial burial depth stress, loading rate, horizontal stress state) on the failure of arch tunnel were revealed based on the orthogonal true-triaxial experiment on cubic granite samples with an arch hole. The results indicate that the true-triaxial experiment reproduces the spalling phenomenon observed in underground tunnel, with a characterization that flake-like rock fragments exfoliated from tunnel sidewalls. The vertical initial fail...
