Tunnel Boring Machines (TBMs) have become prevalent in tunnel construction due to their high efficiency and reliability. The proliferation of data obtained from site investigations acquisition systems provides an opportunity for the application machine learning (ML) techniques. ML algorithms been successfully applied TBM tunnelling because they are particularly effective capturing complex, non-...

Tunnel-boring machine (TBM) tunnelling through an aquifer will generate excess pore water pressures in the soil around tunnel face. Accurately predicting magnitude of is significant because it directly determines effective face support pressure. In this study, analytical solution for transient cylindrical flow caused by TBM considering elastic storage developed. Furthermore, a quasi-static to c...

A tunnel boring machine (TBM) is an important large-scale engineering machine, which widely applied in construction. Precise cutterhead torque prediction plays essential role the cost estimation of energy consumption and safety operation tunneling process, since it directly influences adaptable adjustment excavation parameters. Complicated variable geological conditions, leading to operational ...

The operation data of a tunnel boring machine (TBM) reflects its geological conditions and working status, which can provide critical references essential information for TBM designers operators. However, in practice, may get corrupted due to equipment failures or management errors. Moreover, the state system usually changes, results patterns that vary comparatively. This paper proposes denoisi...

Rockburst disasters frequently occur in deep tunnels excavated by TBM (tunnel boring machine) under complex geological conditions western China. Using FLAC3D, the characterization of a three-dimensional numerical model compound stratum tunnel is conducted, based on water transport project Shanxi Province. Then, characteristics rockburst hard and soft are revealed, energy criteria considering ro...

The article considers the problems of magnetic field distribution, generated by a power electric cable at micro-tunnel-boring shield arrangement site numerical modeling with further full-scale device model experiment. impact foreign sources on readings three-component sensors was established in process study. considerable existence parasitic noises, conditioned external fields and high sensitiv...
