Shin, Y J; Farrokh, E; Jung, J and Kang, H (2025) Optimizing tunnel boring machine operations in real time within defined constraints. Journal of Construction Engineering and Management, 151(6): 04025042, ISSN 0733-9364
Abstract
The optimization of tunnel boring machine (TBM) performance represents a fundamental challenge in underground construction. This study effectively addresses a notable research gap by leveraging a decade's worth of meticulously gathered data from a rotary cutting machine (RCM). By employing dimensional analysis and conducting comprehensive RCM tests, this research develops innovative equations for normal and rolling forces, which are critical factors influencing TBM operations. These equations serve as invaluable tools for optimizing TBM operations under real time conditions. Furthermore, the study introduces a comprehensive methodology specifically tailored to optimize the TBM operation, encompassing essential considerations such as cutter load limits, TBM torque constraints, and cutter geometry. To validate the established formulas and optimization methodology, a pragmatic case study incorporates the TBM advanced driver assistance system (TADAS), effectively demonstrating the practical application and effectiveness of these advancements in real-world construction scenarios. This research significantly contributes to the refinement of TBM operations while effectively addressing practical constraints, thereby fostering improved efficiency and overall performance.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
