Abstract: In this paper, a new method for dam rehabilitation effect evaluation which based on empirical mode decomposition (EMD) was presented. To improve effectiveness of this method, robust estimation theory was applied to separate the environmental trend component. Further, specific example based on EMD proved the effectiveness of the method applied in dam rehabilitating effect evaluation.

摘要： 在介绍经验模态分解方法的基础上，结合补强加固大坝的行为特征，将经验模态分解方法应用到大坝补强加固效果的评价中。为了提高该方法的有效性，还引入了抗差理论进行环境量趋势分量的分离。最后，结合具体实例说明了基于经验模态分解的大坝补强加固效果评价方法的应用。
