Recent advancement in predicting TBM performance

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Tunnel Boring Machine (TBM) may be used for both mining and civil engineering constructions. The majority of tunneling projects is currently carried out by mechanical excavation rather than drill and blast methods since TBM offers numerous advantages, such as; personnel safety, reduced ground disturbance; generates a uniform muck size, and provides a continuous excavation. Accurate estimates of TBM performance are an important part of both a design engineers and contractors working on tunneling project. Without such estimates, it is almost impossible for owners or contractors to make realistic evaluations of the total time and cost required for completing a project. Mechanical tunnels excavated with TBM may also differ from other types of tunneling due to the high level of machine-rock interaction. Intact rock properties, including rock strength and brittleness, and rock mass conditions are a critical parameter for TBM
performance evaluation. Since the first use of a modern TBM occurred in the early 1950s, there have been numerous studies to explain the interaction between rock and mechanical cutting tools. Recently, based on intact and mass rock properties with machine specifications, TBM performance prediction model was developed at the Earth Mechanics Institute of the Colorado School of Mines in the U.S.A. This paper presents the application of TBM in civil engineering practice together within both recent advancement on the CSM model and TBM performance estimation.
