摘　　要：本文基于小波分析理论 ,利用小波去噪技术 ,对一组建筑物变形监测数据进行了去噪处理。实际计算结果表明 ,小波去噪合理有效 ,能够敏感识别观测噪声和有用信息 ,不需要待处理数据的先验知识 ,特别适合于建筑物变形监测的数据处理。Based on the theory of wavelet transform, a new method of using wavelet transform to eliminate the noise of observed data is introduced and an example of calculation also given. The results show that denoise using wavelet transform is efficient and reliable since it is well suited to the processing of building deformation monitoring data due to its sensitivity to the noise of data and capability of identifying useful information.
