Abstract: This article uses GIS data to load groundwater level point data with elevation information, and constructs a groundwater level spatial triangulation using ArcGIS’s 3D Analyst tool. By introducing the Mohr Coulomb failure criterion and solving the equilibrium equation of force or moment, the stability coefficient of the rock and soil mass where groundwater is located is calculated, and based on this, a geological environment stability model for groundwater is established. Calculate the safety factor of groundwater level based on the geological environment stability model, and automatically warn of abnormal changes by combining terminal observations and recorded values. The comparative experimental results show that the design method can achieve continuous automatic warning of groundwater anomalies, and the practical application effect is good.
