Background

Rainfall infiltration is a main factor inducing landslide instability, detection and monitoring of spatial-temporal evolution and distribution of soil underground moisture in the rainfall process can help to understand the mechanism of landslide instability damage, and therefore the purpose of pre-landslide warning is achieved. According to the soil resistivity characteristic, the soil resistivity and the water content are obviously correlated, the time-space response of an active ground electric field in the rainfall process is measured by using a direct current resistance method, and then the water content is calculated by using the resistivity, so that the method is a common monitoring method, and is low in precision and wide in coverage.

At present, the method mainly has a theoretical experimental level, is not widely applied, and mainly has the following reasons:

firstly, the related instruments of the direct current method are used for detection at present, and few instruments are deployed in the field for long-term remote monitoring, so that the acquisition of field data and the summary of application experience are greatly limited.

And secondly, the field environment is complex, the monitoring cost is high, the field environment is not suitable for developing experimental research, and an indoor physical experiment device and related equipment are lacked at present.

Thirdly, rock-soil body in-situ physical parameters are difficult to measure, and have variability in space, so that analysis and research are difficult to develop.

Fourthly, many current experimental devices for rainfall simulation do not have a power supply ground field measurement part, which is mainly because the research purpose of the experimental devices is to research the relation between rainfall and soil strength, and do not relate to the geophysical fields such as a point source ground field.

For the above reasons, in order to facilitate research on the time-space response of the active earth electric field during rainfall, it is necessary to customize and develop a related test device so as to facilitate development of a controllable indoor test.
