| 摘 要： | 在讨论地下围岩应力分布的基础上，用滑移线场理论和Ｍｏｈｒ－Ｃｏｕｌｏｍｂ准则研究了地下洞室围岩进入塑性破坏状态的特征，推导了岩块沿滑移线滑落的条件，得到了岩爆发生时地应力的计算公式．对天生桥引水隧洞的岩爆实例进行了分析和计算，得到了较满意的结果．

| Abstract: | Based on analysis of stress distribution in the wall rocks of underground opening and with the theory of slip line fields and Mohr Coulomb criterion, the characteristic of the plastic failure of the wall rocks has been studied. The slipping condition of the fall of rock mass along the slip line and the formulae for the field stress calculation are derived. The rock burst of diversion tunnel of Tian Sheng Qiao Water Power Station in southwestern China is used as an example to show the feasibility and effectiveness of the method proposed. |
