Keywords:
Factors that determine the selection of method to excavate a tunnel depend upon the geology, economy and site conditions,but when it comes to the economics of tunnelling then it has to be chosen correctly as per the methodology. Cutters are an integral part of a tunnel boring machine and its performance depends largely on these. In order to ascertain various factors of cutters that influence the performance of the machine, a comprehensive study of literature was carried out. The method involved referencing the citations to a particular publication from which the importance of factors responsible for cutter wear in TBM were decided. In order to categorise the impact of different variables on cutter wear, the references were divided into wear, mechanical, geological and engineering categories based on citations reviewed and observed. Cutting conditions of disc cutters has been reviewed and evaluated based on findings of different authors.Abstract
