Sidewall-Based Three-Dimensional DC Resistivity Imaging for Identifying Potentially Water-Bearing Zones Around an Operational Railway Tunnel
Groundwater ingress and moisture-related deterioration threaten railway tunnels in fractured and hydrogeologically active terrains. This study evaluates sidewall-based three-dimensional (3D) direct current resistivity (DCR) imaging for investigating potentially water-bearing conductive zones around an operational railw...
