摘要
盘形滚刀是用在全断面隧道掘进机(TBM)上的重要破岩工具。现阶段,利用全断面隧道掘进机进行硬岩隧道施工时,刀具损耗巨大,致使工期加长、施工效率低下。研究盘形滚刀与岩石的相互作用机理对于指导盘形滚刀选型、盘形滚刀形貌设计以及施工参数的选取都具有重要的理论意义与实践价值。作为开展滚刀-岩石相互作用机理研究工作中的一环,研究方法的设计显得尤为重要。本文介绍了国内外学者常用的研究滚刀与岩石相互作用机理的实验方法与数值模拟方法,分析了各类方法的优劣势,并就相关技术的未来发展进行了展望。
The disc cuter is a key rock-breaking tool used in the tunnel boring machine(TBM).Currently,the cutter wear is severe when the TBM works in a hard rock stratum,which affects the construction speed and cost.The study of the interaction mechanism between disc cutter and rock has an important value on theoretical establishment and engineering application.Research method selection is a kay part of the interaction between cutter and rock investigation.In this paper,the experiment methods and numerical simulation methods used by scholars to study in interaction between disc cutter and rock were introduced,the advantages and disadvantages of each method were analyzed,and the future development of these technologies were prospected.
