In order to effectively identify potential trouble areas of embankments and prevent major flood disasters before they happen

high-density resistivity method was used to measure a dam in Poyang County where the danger situation was serious.24 anomalies were found

including 11 low resistance anomalies and 13 high resistance anomalies. According to the electrical difference between the dam body and the target body of groundwater infiltration

a preliminary analysis shows that the low resistivity anomaly is caused by the dam body being soaked by flood for a long time

the hidden danger site is prone to water seepage

resulting in high local water content and low resistivity. The high resistance anomaly is due to the plugging of the pipe gushing

cutting off the water flow path

forming a hollow structure similar to the network vein

high resistivity. The high-density resistivity method is used to carry out early warning and key monitoring on the sections that may occur danger

and the effect is obvious in the detection of embankment hidden danger

which is worthy of application and promotion in practice.
