为了研究中铁工程装备集团有限公司自主研制的首台TBM的各项技术特点与工程适应性，结合TBM在引松供水工程总干线四标段的掘进施工情况，分析了TBM掘进地层特点以及主要设计参数。引松供水工程四标段掘进岩层复杂多变，富含大量断层破碎地层以及风化灰岩地层，部分地层岩石强度大且石英含量高，对TBM刀盘及刀具要求极高，TBM刀盘面板采用270 mm厚板设计，且刀座基座直接在刀盘面板上加工而成，刀具按非线性方式布置且刀间距控制在82~90 mm；设计了有效的TBM初期支护系统和材料运输平台，并且搭载了激发极化超前地质预报系统。工程掘进结果表明： 该台TBM刀盘设计可靠性强且能保证高效破岩，创造了最高月进尺1 226 m、日进尺70.8 m的优异成绩，TBM在不良地质下支护高效快速，超前地质探测结果可靠，各系统运行情况良好。

The characteristics and main design parameters of largediameter hard rock TBM used in No. 4 Bid Section of the Songhua River Water Conveyance Project are analyzed. The rock strata of the project are complicate; there are many fracture zones and limestone and quartz locally; and it requires highperformance of TBM cutterhead and cutting tools. As a result, the TBM cutterhead is manufactured by 270 mm thickness plate; the nonlinear distance among cutting tools is 82-90 mm; effective primary supporting system and material transportation platform are designed; and advance geology prediction system is adopted. The construction practice shows that the TBM cutterhead designed is reliable and highefficient; the supporting efficiency of TBM in bad geological conditions is high; and the advance geology prediction results are reliable.
