Paper Title:
Coupling Analysis of Seepage and Stress in Jointed Rock Mass of Equivalent Continuum
  Abstract

Under the action of stress and crack hydraulic pressure, the damage and rupture of jointed rock mass accumulate and extend simultaneously during the process of its crack occurrence and growth. The rock mass’s damage will be accumulated owing to its rupture, and the damage is closely related to the rupture. Taking into account comprehensive the stress intensity factors both of plane stress and plane strain for hydrous jointed rock mass, two new equations of crack propagation and the new crack length were built on the basis of energy criterion. Assuming the jointed rock mass as equivalent continuous mass with damage and introducing the damage constitutive equation of rock, the damage evolution of the hydrous jointed rock mass is simulated by the damage tensor and the damage strain. The model is used to simulate one tunnel. Through simulation, the waterhead contour is more smooth when the coupling is considered than is not considered, and the maximal displacement almost the same because the diversion tunnel was bulit.The simulate results can provide a reasonable recommendation to the engineering practices.
