摘要：

The FCSMR classification was formed by combining the fuzzy inference system of fuzzy set theory with CSMR classification. Firstly, the fuzzy inference system was used to deal with the factors' fuzziness of rock slope stability. Secondly, the CSMR classification was used to evaluate stability of rock slope. Both the CSMR classification and FCSMR classification were used to assess the stability of Dachaoshan Hydropower Station water inlet slope. A big planar or soil-like failure was validated by using FCSMR classification while a planar of big wedges failure was validated by using CSMR classification. The results show that planar failure's safety factor is 1.918 and soil-like failure's safety factor is 1.493, which indicates that soil-like failure's probability is higher than big planar and FCSMR classification is more reasonable than CSMR classification.
