Description	Journal: Iop Conference Series: Earth and Environmental Science Based on the typical non-deterministic relationship between the seepage pressure of the earth dam and the upstream water level, this paper proposes a method for establishing a linear regression model for seepage pressure analysis of the earth dam; Taking the Dongzhen Reservoir Dam as an example, two historical data representing osmometers BS3 and BS4 were selected for simulation application, and the reliability test of the regression model was carried out using the correlation coefficient test method. The results showed that the correlation coefficients of the reservoir water level and the seepage pressure monitoring values were 0.911 and 0.850, respectively, and the correlations were good and in accordance with the normal law; By applying the prediction and control functions of the built model, the prediction interval of the monitoring results of the osmometer at different reservoir water levels and the safe variation range of the reservoir water level at different seepage pressure values are obtained. Subsequently, the model was used to analyze and verify the data of all 29 piezometers in Dongzhen Reservoir, and the attribution analysis of the relevant differences.
