摘要
混凝土坝渗漏威胁大坝安全运行,传统渗漏探测手段具有一定局限性,为探究无损检测技术在混凝土坝渗漏识别中的应用,研究以白莲崖水库大坝为例,通过数据去噪和反演,验证了瞬变电磁法在定位渗漏区域方面的可靠性。检测结果显示:瞬变电磁法能够准确识别坝体中的低阻异常区,这些异常区与日常巡视检查发现的渗漏部位具有较高的一致性,表明瞬变电磁技术能够为混凝土坝渗漏治理提供科学依据。
Leakage in concrete dams occurs frequently,posing a threat to their structural safety.Traditional detection methods exhibit certain limitations.highlighting the need for non-destructive techniques to identify leakage.This paper investigated the application of the Transient Electromagnetic Method(TEM)through a case study of the Bailianya Reservoir dam.By performing data denoising and inversion,the reliability of TEM in locating leakage area was verified.The test results indicated that TEM can accurately identify low resistance abnormity area within the dam body,showing strong correlation with leakage areas observed during routine inspections.The findings confirm that TEM technology can provide scientific support for dam leakage management.
