Abstract
Leakage is a common issue in reservoirs; however, accurately detecting its location and seepage diameter can be challenging owing to complex geological conditions. Three-dimensional (3D) resistivity tomography (RT), as opposed to traditional resistivity technology, offers advantages such as high observation density, efficiency, information richness, resolution, and intelligence. This study focuses on the application of 3D RT to diagnose leakage in earth and rock embankment dams. By monitoring the resistance change rate obtained from resistivity image processing, this study accurately assessed the development status of the hidden bodies. This research demonstrates that 3D RT enables rapid comparison of deformation and damage states at different moments, enabling continuous and objective monitoring of earth and rock embankment dams. This technology is comprehensive and provides real-time insights.
