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.
