摘要: 为解决硬岩TBM在硬岩节理密集带地质段施工时,刀盘刀具损坏严重、施工效率低下、施工成本增加问题,针对中天山铁路工程硬岩TBM节理密集段现场施工情况,分析刀盘刀具的主要损坏形式及主要原因,并采取相应的改进措施,使硬岩TBM在节理密集带地质段掘进顺利进行,保证了施工进度,降低了施工成本,对类似工程具有一定的借鉴作用。

Abstract: When hard rock TBM drives through jointdenselydeveloped hard rock section during the construction of Zhongtianshan railway tunnel, the cutter head and cutting tools are seriously damaged, the driving efficiency is lowered and the construction cost is increased. The modes and causes of the damage of the cutter head and cutting tools are analyzed and countermeasures are proposed. In the end, successful driving through the jointdenselydeveloped hard rock section is achieved, the construction schedule is guaranteed, and the construction cost is reduced. The paper can provide reference for similar projects in the future.

Key words: Zhongtianshan tunnel, jointdenselydeveloped section, hard rock TBM, cutter head, damage mode
