摘要 

在隧道项目中,隧道掘进机(TBM)能否顺利施工取决于TBM 系统所有部件(从刀具到后备系统)能否正常运转,并取决于全部机车车辆的配合。而在整个TBM 系统中,刀盘是影响TBM 施工效率最为关键的因素。刀盘的设计影响到掘削效率、刀盘平衡、刀具使用寿命、主轴承/ 齿轮箱维护、出渣效果、面刀和边刀/ 排渣铲斗的磨损情况。总体来说,刀盘设计对掘进速度(ROP)、机器利用率(U)及每日进尺(AR)有重要影响。尽管当前可用文献中已就盘形滚刀、切削力、刀盘的某些设计特征做了讨论,但与本论题相关的文献却十分有限,这是因为刀盘的设计主要由隧道掘进机制造商负责,大部分设计工艺都属制造商专有,虽然本论题当前大受关注,但岩石隧道掘进机的设计对终端客户而言仍是个谜题。本文将试着阐明设计中的基本概念,虽不足以帮助读者进行成熟设计,却可助工程师与承包商理解设计步骤中的构思过程、合理设计中应注意的事项以及刀盘设计对于隧道掘进机运行及寿命周期的意义。

 
Abstract

The success of a tunnel-boring machine (TBM) in a given project depends on the functionality of all components of the system, from the cutters to the backup system, and on the entire rolling stock. However, no part of the machine plays a more crucial role in the efficient operation of the machine than its cutterhead. The design of the cutterhead impacts the efficiency of cutting, the balance of the head, the life of the cutters, the maintenance of the main bearing/gearbox, and the effectiveness of the mucking along with its effects on the wear of the face and gage cutters/muck buckets. Overall, cutterhead design heavily impacts the rate of penetration (ROP), rate of machine utilization (U), and daily advance rate (AR). Although there has been some discussion in commonly available publications regarding disk cutters, cutting forces, and some design features of the head, there is limited literature on this subject because the design of cutterheads is mainly handled by machine manufacturers. Most of the design process involves proprietary algorithms by the manufacturers, and despite recent attention on the subject, the design of rock TBMs has been somewhat of a mystery to most end-users. This paper is an attempt to demystify the basic concepts in design. Although it may not be sufficient for a full-fledged design by the readers, this paper allows engineers and contractors to understand the thought process in the design steps, what to look for in a proper design, and the implications of the head design on machine operation and life cycle.
