AI Technical Summary
Technical Problem
The prior art lacks effective methods to predict the risk of loess wetland in loess wetland areas based on groundwater level changes, resulting in the inability to timely early warning and prevention.
Method used
By obtaining the groundwater level data around the loess wet sink risk area, calculating its average value as the reference groundwater level value, and then calculating the reference soil moisture content, and comparing it with the set threshold, a sink risk warning signal is output.
Benefits of technology
Timely monitoring and prediction of groundwater levels and soil moisture content in loess wet-sink risk areas is achieved, and warnings can be provided before the risk of wet-sink occurs to avoid engineering and geological hazards.

Abstract
The invention provides a geological disaster risk evaluation method and system based on an underground water level, relates to the technical field of geological disaster early warning, and is applied to risk evaluation of a loess collapsing risk district, and the geological disaster risk evaluation method based on the underground water level comprises the following steps: obtaining underground water level data around the loess collapsing risk district, calculating an average value to obtain a reference underground water level value; calculating the reference soil water content through the reference underground water level value; comparing the reference soil water content with a judgment threshold value, and if the reference soil water content is greater than or equal to the judgment threshold value, outputting a collapse risk warning signal. According to the geological disaster risk evaluation method based on the underground water level, quantitative monitoring is carried out on the relationship between the loess collapsible area and the underground water level on the basis of the underground water level, so that the risk of the geological disaster of loess collapsibility in the loess collapsible area can be predicted based on the change of the underground water level.
