Zhang Jianhua. FUZZY OPTIMAL MODEL OF ROCK CLASSIFICATION[J]. Journal of Civil and Environmental Engineering, 1996, 18(1): 90-95. DOI: 10.11835/j.issn.1674-4764.1996.01.013.
This paper proposed a fuzzy optimal model of rock classification
according to a number of controlling factors of rock classification. Satisfactory results are obtained by applying the model to the real rock mass classification.
