Evaluation on country rock quality of tunnel based on set pair analysis

摘要

Based on set pair analysis theory, set pair analysis model of the evaluation on the country rock quality of tunnel has been set up. The identical-discrepancy-contrary system about the correlation degree of evaluation indexes and evaluation factors of the evaluation on the adjacent rock quality of tunnel has been analyzed. The result indicates that set pair analysis model is not only easy calculation but also has merits of high usability of information in the course of evaluation, objective and reasonable system and confidence, etc. This model has been applied to analyze the evaluation on the country rock quality of tunnel in Maluping mine. The application shows that the model is effective and practical.
