摘要： 无模糊度和整周跳变问题的单历元GPS变形监测数据处理方法可快速提取监测点的变形信息，特别适用于形变量较小的短基线高精度工程变形监测领域。应用小波多尺度分析方法对染噪的GPS变形监测数据序列进行异常值探测与降噪处理，可有效提取弱小的变形特征信息，提高GPS变形监测的精度。汉源新县城GPS变形监测数据的实例分析验证了该方法的正确性、有效性和可靠性。

Abstract: Single epoch GPS deformation monitoring data processing method without ambiguity and cycle slip problem can quickly extract the information of monitored deformation, especially suitable for the deformation monitoring of project with short baseline and high precision whose deformation is tiny. Wavelet multi-scale analysis method is applied to outlier detection and noise reduction of GPS deformation monitoring. The tiny deformation characteristics is extracted effectively and the precision of GPS deformation monitoring is enhanced. The analysis on GPS deformation monitoring data of Hanyuan new county validated the correctness, validity and reliability of this method.
Key words: GPS, safety monitoring, single epoch, wavelet multi-scale analysis
