【Abstract】

<正>This paper builds generalized model for jointed rock mass under hydrodynamic pressure and analyses the influences on the stress distribution and damage evolution of rock mass with finite element analysis software. As well as that,it analyses the change of permeability during the multicrack propagation and transfixion process of rock mass,and builds the permeability-stress coupling equation that describes the damage and frac-
