介绍了自适应过滤法原理及计算方法,利用自适应过滤法模型预测了大坝变形趋势。实际数据计算结果表明:自适应过滤模型预测精度优于传统的回归分析法,在大坝监测预报中是有效可行的。
The principle and calculation method of adaptive filtering are introduced, and the deformation trend of the dam is predicted by the adaptive filtering model. The calculation results of actual data show that the prediction accuracy of adaptive filtering model is better than the traditional regression analysis method, which is effective and feasible in dam monitoring and forecasting.
