Empirical Mode Decomposition(EMD) method has an advantage of doing adaptive filtering noise cancellation according to characteristics of the signal itself.In the paper,the point EMD method is applied to deformation monitoring data processing for high-rise building.By analyzing practical deformation monitoring data,it is shown that excellent denosing results can be obtained by using EMD method.Besides,this method can efficiently extract weak deformation characteristics information from data series having strong noises.
