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.
