摘　　要：为解决国内大量全断面隧道掘进机(TBM)未能全寿命使用,以及损伤修复相关问题。通过查阅国内外文献资料,分析TBM刀盘疲劳、磨损、蠕变、断裂等因素的影响程度,研究刀盘微观裂纹扩展机理,结合TBM刀盘特定服役环境(地质参数、结构参数、操作参数等)构建多元损伤模型,从再制造刀盘方面提出了多元损伤耦合框架。This paper is to solve the problem that the large number of full face tunnel boring machine （TBM） can not be used in the whole life, as well as the related problems of damage repair. By reviewing the literature at home and abroad, we analyze the influence of TBM cutter wear, fatigue, creep, fracture and other factors, the micro crack propagation mechanism of cutter. The multiple damage model under TBM specific service environment （operating parameters of geological parameters, structure parameters, etc.） is built. In this paper, the multiple damage coupling framework is put forward from the aspect of remanufacturing cutter head.
