The construction of an online real-time resistivity monitoring system on the reservoir dam can effectively monitor the resistivity changes of the dam body in real time. The high-density electrical method instrument, through the observation of soil resistivity, can very intuitively present the changes in soil moisture content such as water level variations and dam seepage. Especially for minor internal seepage, it can be detected early. The system software can convert the resistivity change data into a chart with stratum structure, which is more intuitive. Continuous online monitoring data can be obtained and transmitted in real time to the cloud server center via wireless network to achieve remote monitoring of the embankment situation. This is conducive to comprehensively, scientifically and truly reflecting the seepage situation of the embankment, providing supervision means for real-time monitoring of the embankment.
