摘要： 采用试验方法研究了盘形滚刀破岩时掘进参数贯入度、切削速度和刀间距的选择对破岩性能的影响.结果表明:贯入度、切削速度的增加，破岩力成比例增大；得到最优贯入度为76mm和最优切削速度6m/h，进而确定刀盘转速和最外径线速度，推算TBM总推力和总转矩.分析盘形滚刀切割岩石时的挤压、剪切破坏过程，前方破碎区由于挤压破坏形成粉盒区；两侧的岩石受到滚刀浸入的挤压作用，发生弹性变形，逐渐达到岩石的剪切强度极限，裂纹贯通碎裂.

关键词: 贯入度, 切削速度, 刀间距, 参数选择, 压剪分析

Abstract: The rockbreaking performance was studied in the liner cutting test based on different cutting parameters， especially on penetration depth， cutting speed and cutter space. The test results show that the rockbreaking force is increased with the penetration depth and cutting speed. The optimal penetration depth and cutting speed are 76mm and 6m/h in current project. Both the total thrust and torque could be calculated from the maximum linear velocity and rotating speed of cutter head. Attrition crushing was occurred and powder district was formed in the front side of the disc cutter， while the sides will be under the extrusion force and gradually reach the ultimate strength of shear leading to fragmentation.

Key words: penetration depth, cutting speed, spaces, parameters selection, compression and shear analysis
