摘要：In the stage of sites selection of high-level waste geological repositories, reasonable division of homogeneous zones of rock mass structure is helpful to further analyze the suitability of engineering rock mass quality and construct discontinuous fracture network model. Based on accurate measurement of surface structural planes, the surface rock mass structure in the study area is differentiated by discontinuities spacing, and the homogeneity of rock mass structure is evaluated by linear density index. The results show that the rock mass structure type in the study area is dominated by sub-blocks, and its distribution area accounts for 84% of the total area. The study area belongs to homogeneous rock mass structure with high similarity. Most of the surveying lines in the study area have high correlation and uniform joint density.
