【摘要】 根据Criffith理论,应用脆性断裂力学中的自持续断裂概念和能量原理,建立了地下洞室中岩爆的一般判据,并根据势能驻值原理,阐述了判据的一般性,分析和具体列出了均匀应力场中圆形洞室的岩爆判据,并将其应用于锦屏水电站引水隧洞岩爆分析的实际工程中。更多还原

【Abstract】 Based on Griffith’s theory.brittle fracture mechanics and conservation-of-energy principle,the author set up popular criterion on rockburst in underground caverns, and provided rockburst criterion of circle caverns in uniform stress field.As an application, the diversion tunnel in the Jin Ping Hydropower Station is analysed by this criterion.更多还原
