Performance analysis of tunnel-boring machine by probabilistic systems approach

, 2018
In this paper, the performance of an earth pressure balance tunnel-boring machine (EPB-TBM) during tunnel construction is analysed. A case study with data from the east–west part of the Tehran metro line 7 is employed to develop a methodology.
