Structural plane is an important influencing factor for the rock mass quality, 3D modeling, borehole hydraulic test and engineering design of underground research laboratory. Xinchang rock mass in Beishan area has been chosen as the preferred site for URL on geological disposal of high-level radioactive waste in China. The characteristics of structural plane in Xinchang rock mass were obtained based on acoustic borehole televiewer and other geological information. The results indicate that the granite rock mass with a high massiveness is beneficial for construction of URL. The width of faults around the preferred site and incidence in horizontal and vertical directions decrease with the depth. Characteristics of dip and strike of structural plane are the same as features of other structures in this area. The research results provide meaningful information for design of URL and further geological research.
