Before the underground structures such as tunnels will be constructed, because of the sensitivity for the water included for the rock mass, electrical prospecting for geological surveys is often executed. However, the relationship between resistivity and the physical property of the rock mass has not quantitatively been clarified. Especially, in the jointed rock mass, it is important to grasp the influence of the joint for the resistivity. In this paper, 2 kinds of jointed rock mass model are made. One is the discontinuity model, which is made to change the open width of discontinuity by intervening the various number of filter paper for discontinuity. The other is the heated model, which is generated the micro opening crack inside of the rock by heating by the electricity muffle furnace. And then, using these models, the characteristics of resistivity for the jointed rock mass are examined.
