In order to ensure the safe and stable operation of the dam,a combined safety monitoring model is built by using statistical model and finite element deterministic model to analyze the horizontal displacement,uplift pressure and stress of the dam.The research results show that the error between the predicted horizontal displacement of the combined monitoring model and the measured value is less than 0.14mm,the prediction error of the uplift pressure of the dam foundation is less than 0.93kPa,and the prediction error of the stress is less than 0.81MPa,with high prediction accuracy.The results show that the combined model can effectively monitor and forecast the dam operation behavior,and has important value in preventing the occurrence of major dam safety accidents,and can help improve the safety and stability of the construction of water conservancy projects.
