| Full face rock tunnel boring machine(TBM) becomes more and more important in current tunnel construction.Disc cutters are the most serious weared and frequently changed parts,and have a big portion in construction cost.Based on the theoretical framework research on the management theory of disc cutters' service life and its relevant techniques,analysed the characteristics of disc cutters' rock-breaking,and discussed the relevant theory and calculation formula which can be available under different geological situations.Combines with the TB880E type TBM adopted in Qinlin Tunnel construction, bulit life prediction and management model of TBM disc cutters,and developed cutters management software whose functions include display the positions of disc cutter,replace broken cutters,display the results of cutter replacement and manage the database. |
