Abstract The correlation between joint trace and aperture has an effect on the distribution and permeability of joint network. Finally，the hydro-mechanical behavior of fractured rock mass is influenced. Based on nuclear disposal project in Sellafield，the correlation between joint trace and aperture was studied when they followed the power-law distribution. With discrete element software UDEC，the effect of correlation between joint trace and aperture on hydro-mechanical behavior of fractured rock mass was analyzed. At the end，a calculation system was proposed to do the hydro-mechanical calculation for fractured rock mass considering the correlation between joint parameters. It is concluded that correlation between joint trace and aperture has a significant effect on hydro-mechanical behavior of fractured rock mass. When the correlation between joint trace and aperture was power-law function，permeability tensor and representative elemental volume(REV) of fractured rock mass increased.

Key words： seepage mechanics hydro-mechanical coupling permeability representative elemental volume correlation power-law distribution
