Comprehensive Ahead Prospecting of Tunnels in Severely Weathered Rock Mass Environments with High Water Inrush Risk: A Case Study in Shaanxi Province
The ahead geological prospecting of severely weathered surrounding rock in a tunnel is challenging due to complex geological conditions.Hence, the best approach is to use a variety of geophysical exploration methods.In this study, we have applied seismic, electrical resistivity (ER), and transient electromagnetic (TEM) methodologies for ahead prosp
