摘要：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.
