Abstract: TBM tunneling technology in weak phyllite section is presented in terms of tunneling management, TBM boring parameter adjustment, collapse treatment and equipment modification. The practice shows that the speed and efficiency of TBM tunneling in weak phyllite section can be improved by means of equipment modification and adopting rational boring parameters. 

Key words: TBM, weak phyllite, equipment modification, boring parameter
