The quantitative estimation of the time dependent behavior of a host rock is important to confident the design of a plug in HLW repository. On the other hand, interaction between rock and groundwater may affect with the time dependent behavior. Therefore, it is need to establish the model such a coupling process and estimate a distribution of micro crack in rock quantitatively. The paper report the results of the study on evaluation of the properties of a crystalline rock using of surface wave for these purpose.
