中文摘要：
为了研究岩桥拉张破坏规律,采用有限元软件FEPG,对不同倾角岩桥拉张破裂过程进行数值模拟.模拟结果显示,在单轴压缩条件下,对于同一裂纹角度、相等距离的两组平行预裂纹,在不同的岩桥倾角条件下,预裂纹扩展程度不同;岩桥倾角越大,岩桥越容易拉张破坏.
英文摘要：
In order to study the tensile failure of rock bridge,the finite element software FEPG is used to simulate the tensile failure process of rock bridge with different angles.Under the condition of uniaxial compression,the simulation results show that for two sets of parallel pre-cracks with same crack angle and distance,but with different inclination of rock bridge,the extension level of pre-crack is different.The bigger the inclination angle of rock bridge,the easier the rock bridge goes to tensile fracture.
