TBM施工隧道围岩分级方法研究

STUDY ON SURROUNDING ROCKMASS CLASSIFICATION OF TUNNEL CUT BY TBM

随着隧道工程建设的发展,全断面隧道掘进机(TBM)在隧道施工中必将占有越来越重要的地位,传统的隧道围岩分级难以满足TBM施工条件下的隧道施工需要。因此,研究TBM施工条件下的隧道围岩分级,是采用TBM进行隧道施工的需要。结合西(安)—安(康)铁路秦岭隧道TBM施工研究,提出了TBM施工条件下的隧道围岩分级方法。

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.
