Cutter force measurement on tunnel boring machines – Implementation at Koralm tunnel

Loading of a disk cutter on tunnel boring machines (TBM) is usually estimated from global machine thrust. In order to be able to measure cutting forces of an individual disk cutter, a new measurement method was developed and published in a previous paper (Entacher et al., 2012). This study presents the implementation process of the measurement method at the first TBM of the Austrian Koralm tunnel. Results show that peak forces are a multiple of average forces and that the distribution of forces across the tunnel face can be very irregular. The occurring forces are in very good agreement with geological features of the tunnel face such as highly fractured zones and orientation of schistosity.

Causes of reduction in shield TBM performance - A case study in Seoul

This study investigates the fundamental reasons of reduction for excavation performance on shield TBM in the Han River riverbed tunnel by means of analysis of field measurement data. For the study: (1) measurement data were analyzed by both the thrust and penetration rate data in a given section with rock types and direction types, (2) a number of disk cutter consumption and types of abrasion were analyzed, (3) an exhaust ratio of screw conveyor and design problem of screw conveyor were analyzed by earth mud which becomes the rock powder. As a result of this study, it was found that the lack of penetration depth caused by lower thrust, disk changes according to rapidly changing rock types, and installed angle of screw conveyor, play an important role in the excavation performance.
