A full face rock tunnel boring machine was highly sensitive to geologic situation. 全斷面巖石掘進(jìn)機(jī)施工對(duì)地質(zhì)地層狀況非常敏感。
Correctly determining quality parameters of rock is the theoretical basis of use of TBM(full face rock tunnel boring machine)and its design. 正確確定巖石的性能參數(shù)是全斷面巖石掘進(jìn)機(jī)使用及高性能全斷面巖石掘進(jìn)機(jī)研制的理論基礎(chǔ)。
Being a crucial factor in influencing the performance of Full Face Rock Tunnel Boring Machine (TBM), the cutterhead design is one of the key issues of TBM. 刀盤(pán)設(shè)計(jì)是全斷面巖石隧道掘進(jìn)機(jī)（TBM）的設(shè)計(jì)關(guān)鍵，是影響其掘進(jìn)性能的決定性因素。
