The invention relates to a wall rock support method for an extremely strong or a strong or a moderate rock burst tunnel section that is deeply buried in an underground chamber.
因而认为，进行高压渗透试验，可以更为真实地反映深埋地下洞室围岩体的渗流状态。
Therefore, it is thought that the seepage behavior of rock masses surrounding the underground chamber can be reflected really by carrying out HPPT.
