In the process of design and construction of underground building,the stability of surrounding rock should be appraised comprehensively.Based on the fuzzy set theory founded by the author,the recognition method of variable fuzzy pattern is suggested in this paper.Its key contents include two formulas of the relative membership degree level and nonlinear analysis of the variable fuzzy pattern recognition model and the combinations of variable model under different parameter circumstances.The proposed method is used to appraise the surrounding rock stability of the underground building in Shui Buya Hydro Project.The results show that the appraisal is more reasonable than those obtained by the method based on extenics theory.
