Abstract
Conducting safety evaluations for dams holds significant engineering importance.This study applies geological mapping and the high-density electrical method to investigate the dam and its surrounding environment.Through geological data processing,interpreted geological maps are obtained.Inversion processing of high-density resistivity data generates an underground resistivity model of the dam area.The results indicate:The bedrock of the dam foundation is intact,with localized weathering observed;low-resistivity anomaly zones,identified as seepage zones,fractures,and water-filled cavities,are detected in different dam sections.The weathered structures,fractures,and seepage zones at the reservoir bottom constitute potential pathways for excessive water loss from the dam,and cavities within the dam foundation pose potential threats to dam safety.关键词
