摘要
本文在文献[1]的基础上,进行了岩石蠕变损伤分析,结合非线性力学几何场论,推导出岩石损伤、岩石蠕变损伤非线性大变形有限元公式。结合地下工程的特点,进行了相应的有限元程序设计,对节理岩体下开采问题进行了数值模拟,取得了较满意的结果。
Based on Ref.〔1〕,rock creep damage is analysed.Combining with geometry field theory of nonlinear mechanics,nonlinear finite element formula of rock creep damage for large deformation are derived.The related finite element programs, in which characters of underground engineering are considered,are compiled. Numerical modelling of extraction in jointed rock masses is examined,and a good result is obtained.
