硬岩掘进机刀盘纯切削扭矩计算研究

根据硬岩掘进机盘形滚刀在岩体开挖面上滚压切削的实际状态，以刀刃下的岩石受滚压破坏并沿刀刃两侧软弱面崩落为机理，以岩石强度极限为材料常量依据，试推导滚刀切削牵引力以及刀盘纯切削扭矩的计算方法。在推导过程中，不考虑岩石为什么会被破碎或怎么破碎，仅考虑岩体受力状态,以实际工程掘进报告比较计算结果。

Study on Cutting Torque Calculation of Cutterhead of Hard Rock TBMs

In order to deduce the calculation method for the cutting tractive force and for the cutting torque,the author uses rock strength limit as material constant and relies on the actual state of the rolling cutting in TBM boring and the mechanism of the crushed rock falling along the weak area on both sides of the cutting edge.The author makes comparison and contrast between the calculation results and the actual boring records.In the whole deduction process,the author takes the loading conditions of the rock i...
