Abstract
Rockburst is a common dynamic failure phenomenon in deep-buried underground construction process, which greatly threatened the safety of equipment and person. In the paper, combined with the engineering of Xinjiang Xiabandi hydraulic and the Russense’s rockburst criteria, the finite element analysis are employed to study the effect of advance dig-hole and softening of surrounding rock. The results of the study indicate that the two measures can effectively reduce the intensity of rockburst level in the construction of deep-buried tunnel.
