Abstract With the development of the tunneling engineering，the applicationg of TBM will play a more important role in tunnel construction. As a matter of fact，the traditional surrounding rockmass classification can not meet the need of tunnel construction by TBM and the study of surrounding rockmass classification in tunnel excavation with TBM is necessary. Such a surrounding rockmass classification method is proposed with the practice in construction of Qinling tunnel and Xian—Ankang railway line.

Key words： tunnel excavation by TBM surrounding rockmass classification
