Abstract
This paper presents the fundamental study on drag force of shield TBM cutter bit by scaled model test. Several theoretical analyses of the drag force of cutter bit have been studied. However, there are still some difference between the theoretical approaches and actual drag bit capacity. In order to study the drag forces of shield TBM cutter bit, the scaled model tests are carried out and analyzed. The results obtained from scaled model tests are compared with the existing theoretical equations. It is highly expected that the results of this study will be very essentially useful to design and develope the TBM cutterhead.
