DOI: 10.1007/s11356-020-09969-6
Abstract: Tunnel boring muds, coming from underground works, are considered as specific materials due to their intrinsic characteristics (granularity, clay content, water content, presence of heavy metals). In order to determine if they can be valorized… read more here.

DOI: 10.1007/s12205-019-0302-0
Abstract: The performance of earth pressure balanced tunnel boring machines (EPB-TBM) is dependent of a variety of parameters. Moreover, these parameters interact in a rather challenging way, making it difficult to adequately model their behaviour. Artificial… read more here.

DOI: 10.1016/j.jappgeo.2018.03.017
Abstract: Unexpected geological structures can cause safety and economic risks during underground excavation. Therefore, predicting possible geological threats while drilling a tunnel is important for operational safety and for preventing expensive standstills. Subsurface information for tunneling… read more here.
