基于鲁棒性回归方法的大坝安全监控混合模型研究

Research on Hybrid Model of Dam Safety Monitoring Based on Robust Regression Method

为了避免大坝损坏造成严重的、不可预知的损失,需要对大坝进行安全监控。以某水库大坝为例,研究了鲁棒性回归方法在大坝安全监测混合模型中的应用可行性。结论显示,该方法的各个预测指标均明显优于传统的最小二乘法估计,基于鲁棒性回归方法的大坝安全监控混合模型可以用于大坝安全监控预测研究。

In order to avoid serious and unpredictable losses caused by dam damage,it is necessary to carry out safety monitoring of the dam.Taking a reservoir dam as an example,this paper studies the feasibility of the application of robust regression method in the hybrid model of dam safety monitoring.The conclusion shows that the prediction indexes of this method are obviously due to the traditional least squares estimation.The hybrid model of dam safety monitoring based on robust regression method can be used for dam safety monitoring,control and prediction research.
