AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

本发明公开了一种岩体节理组数及产状的统计方法,其选择待测岩体区域中至少两条方位相交的测线来测量其结构面产状;根据测量得到的结构面产状制作玫瑰花图,在玫瑰花图中划分为节理组,确定每个节理组的走向边界线及走向线;并根据测量得到的结构面产状制作极点等密度图,依据玫瑰花图中节理组的划分区域在极点等密度图中相应圈定出各个节理组区域,得到待测岩体区域的节理组数及优势结构面产状;本发明将玫瑰花图中的规模值及极点等密度图中的发育程度值相结合,综合对岩体节理组进行分组,统计出与实际情况相符且更准确合理的岩体节理组数及产状,进而能够保证岩体质量Q系统分级和定性判定巷道、边坡台阶稳定性等结果的准确性。
