摘　　要：为了保障大坝安全稳定运行,利用统计模型和有限元确定性模型构建安全监控组合模型,对大坝的水平位移、扬压力和应力进行分析。结果显示,组合监控模型的水平位移预测值与实测值的误差小于0.14mm,坝基扬压力预测误差小于0.93kPa,应力预测误差小于0.81MPa,预测精度较高。研究表明,组合模型能够对大坝运行性态进行有效监控和预报,对防止大坝重大安全事故的发生具有重要价值,可为提升水利枢纽工程建设安全稳定性提供帮助。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.
