Sažetak

The statistical homogeneity of rock mass has always been an important issue in rock mass engineering. The rock mass of national underground oil storage in Huang Island is analyzed in this study with focus on the division of a statistically homogeneous area. Trace length is a basic element in determining crack features. The rock mass of different track lengths differs widely in terms of mechanics and deformation characteristics. This study includes trace length information in the division of a statistically homogeneous area and considers the variances and mean values of crack samples in different regions separately by F-test and T-test to determine if the samples have statistically similar trace length information. Numerous crack samples are required to divide a statistically homogeneous area. This study adopts the Watson test to divide a statistically homogeneous area and considers data on crack occurrence to achieve the purpose of obtaining fewer samples for occurrence comparison. Crack occurrence and trace length information are considered by integrating F-test, T-test, and Watson test to gather adequate basic information on cracks and obtain objective and reasonable results for statistical homogeneity.
