AI Technical Summary
Existing technologies lack a unified method to accurately count the number and occurrence of rock mass joint groups, resulting in insufficient accuracy in the Q-system classification of rock mass quality and qualitative assessment of the stability of roadways and slope steps.
A method combining rose diagrams and pole isodensity maps was adopted. The attitude of the structural surface was measured by selecting at least two intersecting survey lines, joint groups were divided, and the strike boundary lines were determined in the rose diagram. The joint group regions were delineated by combining the pole isodensity map to ensure the accuracy of the statistical results.
This improved the accuracy of statistics on the number and occurrence of rock mass joints, ensuring the accuracy of rock mass quality Q-system classification and qualitative judgment of the stability of roadways and slope steps.
