Abstract: There are some reasons to engender the rock-burst such as the rock post-peak behavior, which is the radical reason, and geological factors, which are exterior. After analyzing the energy releasing and gathering and transferring in surrounding rocks during the excavation in underground projects, it is discovered that the high stress is one of the important factor to engender the rock-burst. Character of engendering the rock-burst in space-time appears in step of plastic intenerated deformation. And the conditions of rock-burst are studied with nonlinear analysis. So the results are that the stability of the rock is connected with the size of the rock and physical characteristic of demolished rock. And the criterions are following the equations, and < .

Key words: rock-burst, high stress, rock post-peak behavior, nonlinear analysis
