摘要: 刀盘是全断面硬岩掘进机(TBM)的核心部件,其结构的地质适应性是决定TBM掘进效率的关键因素。根据TBM刀盘制造企业设计的实际需要,制定了刀盘设计基本流程,结合掘进地质条件、刀盘结构参数和掘进参数,建立了刀具布置、开口、盘体设计等关键参数计算模型,提出相应的TBM刀盘地质适应性设计方法。将TBM刀盘设计方法应用于某供水工程,对该工程所用TBM的刀具布置参数、刀盘驱动性能与掘进参数以及刀盘结构参数进行地质适应性设计,并对设计方案进行了力学性能和出渣性能仿真分析。研究结果表明,刀盘设计方法能有效实现刀盘结构、刀具布置以及相关掘进参数地质适应性设计,所设计的刀盘力学性能满足施工要求。目前该刀盘在引水工程中累计已掘进12 km,工作状态良好。

Abstract: The cutterhead is the core component of the full-face rock tunnel boring machine (TBM). The geologic adaptability of the structure is the key factor in determining the TBM efficiency. The basic process of cutterhead design is formulated based on the actual needs of designing cutterhead in TBM manufacturing enterprises. The key parameters calculation models of cutter layout, opening, and cutterhead body design are established by combining geology parameters, cutterhead structure parameters and tunneling parameters. The TBM cutterhead design method is applied to some water supply project. The parameters of TBM cutter layout, the driving performance of the cutterhead, tunneling parameters and cutterhead structure parameters are designed geology-adaptively. The performance of the design program is simulated and analyzed. The research results show that the cutterhead design method can effectively achieve that the cutterhead structure, the cutter layout and the relevant tunneling parameters are designed geology-adaptively. The mechanical properties of the cutterhead is designed to meet the construction requirements. At present the cutterhead has tunnelled 12 km in the water supply project and work well.

Key words: cutterhead, engineering application, geological adaptability, structral design
