| 英文摘要 | Morphology and shear strength assessment is vital for jointed rock mass geomechanics. The measurement point interval ( d I p ) significantly impacts joint precision in shear tests. A study on 45 joints using six statistical parameters over 500 intervals classified three morphological stages: steady decline (I), sharp drop (II), and fluctuations (III). Smaller d I p increases data volume but not accuracy, impairing efficiency. Thus, a model was created for Stage I stability. Insights guided the selection of an optimal d I p , maintaining details and facilitating processing. A link between common 2D parameters and the Joint Roughness Coefficient ( JRC ), incorporating the optimal d I p range, was established. The correlation between joint size and interval choice was examined. Results displayed diverse size effects (positive, negative, or neutral) depending on d I p and metrics. Though interval influence patterns remained constant, Stage I showed that larger joints can tolerate wider intervals without precision loss, suggesting larger d I p s for large joint evaluations. |
