In June 2017, a high-density electrical resistivity tomography (ERT) profile and multiple sensor measurement points were arranged on the slope to the southwest of the meteorological station in Baota District, Yan'an City, Shaanxi Province. A relatively complete rainfall infiltration observation system was established to conduct long-term field monitoring. The rainfall infiltration monitoring system consists of a power supply and network subsystem, a sensor subsystem, a data center subsystem, a high-density electrical method subsystem, and a monitoring subsystem. The high-density electrical equipment mainly comprises a computer, a working condition host, connecting cables, acquisition boxes, and electrodes.
Currently, this system is equipped with 10 acquisition boxes for electrical equipment, each containing 8 electrodes, totaling 80 electrodes. During installation, the electrode profile was perpendicular to the slope edge and installed at a horizontal distance of 0.5 meters apart. A total of 27 electrodes were installed on the upper platform of the slope, and the rest were installed on the slope in sequence. Long-term monitoring of the hydrological processes on the slope was achieved through high-density electrical methods. The monitoring data was inverted to obtain resistivity data.
Achieving long-term monitoring of slope hydrological processes through high-density electrical methods.
The data provided are original monitoring data without any processing or modification.
The installation and operation of the monitoring equipment comply with work specifications and operating procedures, ensuring that the obtained raw data is true and reliable.
