Coupling analysis of seepage and stress in fractured rock mass based on the distinct element method

    • Abstract
  • Based on the postulation of the distinct element method and the characteristics of fluid flow through joint networks of rock mass and taking the change in joint width as ligament,the fracture network model of the coupled seepage and stress fields in fractured rock mass is studied.The coupled and uncoupled analyses of the stress field and seepage field combining a computation example are studied respectively with the distinct element method.The results show that the stress,displacement and seepage discharge of coupled analysis are larger than those of uncoupled analysis.Therefore more actual and securer resolution can be obtained when the coupling of stress field and seepage field are considered.
