Accurately predicting tunnel boring machine (TBM) performance is beneficial for excavation
efficiency enhancement and risk mitigation of TBM tunneling. In this paper, we develop a …

The accurate estimation of disc cutter wear has always been a long-term topic affecting the
excavation efficiency and construction cost of tunnel boring machines (TBMs), especially in …

The rock-cutting mechanism and force prediction model of disc cutter considering the effect
of dense core are proposed in this study. According to the working characteristics of disc …

The rock cutting performance and cutter-rock contact behavior of partial-worn cutters are
investigated via scaled rock cutting experiments. The results reveal that the partial-wear of …

Disc cutters wear and need to be replaced when using tunnel boring machines (TBMs) to
excavate through rock, often becoming a high ticket item on the list of consumables in …

In this study, the correlation between the uniform wear volume of the disc cutter and the
normal load is established based on a principle of microcutting plastic removal of abrasive …

On the background of a subway project in Suzhou City of Jiangsu Province and targeting the
engineering difficulty of disc cutters cutting reinforced concrete walls, this paper illustrates …

When shield machine traverses through hard rock mass, disc cutters will be abraded to
different degrees. Excessive height difference exists between adjacent disc cutters, which …

The complex interaction between the cutters and rocks in the tunnel face makes it difficult to
predict the cutter wear, exactly. Therefore, many researchers have tried to study this process …

Partial wear is one of the fatal abnormal wears, which may pose a threat to the cutterhead or
even the driving system. Considering the randomness of partial wear, the real-time detection …
