The subject of underground utilization whose representative is radioactive waste disposal sites has enhanced the importance of investigating the shear-flow characteristics of the rockmass as a natural barrier. In this study, the joints which have been given the prescribed shear history are used to examine the effects of past shear histories on the shear and hydraulic properties. As a result, some interested characteristics are obtained. Shear stress doesn't show a peak in all the normal stress ranges by the effects of preceded shear histories, even if the normal stress is higher than experienced one. Dilation and hydraulic conductivity have an intimate correlation to each other. Hydraulic conductivity of a historical joint is small on increasing rate and changing quantity, whereas that of a non-historical joint rapidly increases in the initial state of shearing.
