DESIGN OF FUZZY INFERENCE SYSTEM FOR CLASSIFICATION OF UNDERGROUND CONSTRUCTION SURROUNDING ROCK

Regarding several main factors influencing the classification of underground construction surrounding rocks as the fuzzy subsets in evaluating surrounding rock classification, and using a fuzzy inference system established for the underground works surrounding rock classification, we can obtain the result of the detemined rock types consistent with the actual local case. The result provides a basis for information design and construction of underground works.
