摘　　要：堤防渗漏是堤防工程常见险情之一,性质上多表现为隐蔽性、随机性,早期特征不明显,堤防渗漏隐患部位的准确探查对堤防工程渗漏隐患的防控具有重要意义。瞬变电磁法具有分辨率高、探测速度快、操作简便等特点,适用于堤防渗漏隐患探测的要求。以长江南京段江心洲堤防工程为探查目标,采用等值反磁通瞬变电磁物探技术进行渗漏隐患探测,通过对数据资料进行处理与分析,验证了该方法的可靠性,可为汛期堤防险情排查提供参考。Dike leakage is one of the common dangers in dike engineering,which is mostly hidden and random in nature,and the early characteristics are not obvious.The accurate detection of the hidden danger of dike leakage is of great significance to the prevention and control of the hidden danger of dike engineering.The transient electromagnetic method has the characteristics of high resolution,fast detection speed,and easy operation,which is suitable for the detection of hidden dangers of dike leakage.This study takes the Jiangxinzhou dike engineering in the Nanjing section of the Yangtze River in Jiangsu Province as the exploration target,and uses the equivalent inverse flux transient electromagnetic geophysical technology to detect leakage hazards.Through data processing and analysis,the reliability of this method has been verified,which can provide reference for the investigation of dike hazards in the flood season.
