It calculates the cloud mode membership degrees via instituting multi-leve quantitative system and assessment leve standards of the surrounding rock mass . It then determines the engineering geology classification of the surrounding rock mass by combining qualitative assessment with quantitative classifying results . Through engineering practices , it is shown that the cloud mode theory unifies the ambiguity and randomness associated with the conventiona surrounding rock mass classification . Its results are compared with determined by severa geologica engineers . This comparison shows that the results of identica in 14 sections among the tota 1/ sections . The new method has high practicable for the classification of the surrounding rock mass of tunne . Key words Cloud mo
