Safety early warning method and system applied to hydrogeological exploration scene

The invention relates to a safety early warning method and system applied to a hydrogeological exploration scene. The method comprises the steps that in the water pumping test process, a depth reduction value point of an observation hole is drawn to obtain a corresponding depth reduction change curve, and the depth reduction change curve comprises a depth reduction turning point; taking the drawdown turning point as a fixed clustering center, performing clustering analysis on the drawdown value points, and determining a bending curve of a middle area of the drawdown change curve; calculating an error between the bending curve and a standard curve; and performing safety early warning based on the error. By means of the technical scheme, safety early warning in the water pumping test process can be achieved, normal proceeding of the water pumping test is ensured, then the accuracy of hydrogeological parameters is ensured, and potential safety hazards in production operation are reduced. 本申请涉及应用于水文地质勘查场景下的安全预警方法
