岩石掘进机盘形滚刀前倾及内倾安装的理论探讨

Theoritical discussion for disc cutter inclined forward and inward of TBM

通过对全断面岩石掘进机正安装盘形滚刀破岩过程的分析，提出在刀盘上采用前倾安装或内倾安装的盘形滚刀，对提高盘刀寿命及其破岩效率有一定现实意义。

Based on the analysis of the process of innercutter of full face rock tunnel boring machine,we may use thedisc cutter inclining forward and inward on cutterhead. This ispractically important in prolonging cutterhead's life and improving its rock-cutting efficiency.
