The measured deformation data contain rich temporal and spatial information and evolution laws of dam deformation. To study the co-integration relationship of the aging deformation of extra-high arch dams, wavelet decomposition was firstly used to obtain the aging component of the dam displacement. Considering the weak spatial integrity of extra-high arch dams, the FCM clustering algorithm was utilized to realize the regionalization of aging deformation. With the help of the idea of regional linearization, the spatial nonlinear co-integration relationship of the whole dam aging deformation was transformed into several approximate linear co-integration relationships within different regions. The zonal co-integration model was established to describe the development law of time-varying co-integration in different regions of the dam. The co-integration development monitoring and early warning of multi-measuring points aging deformation were realized by co-integration residual.

实测变形资料作为特高拱坝服役性态最直观的表征，蕴藏着丰富的时空信息和演变规律。为研究特高拱坝时效变形的协整性，利用小波分解获得大坝位移的时效分量，考虑到特高拱坝的空间整体一致性差异，采用FCM聚类算法实现了时效变形的区域化，借助区域线性化思想，将整个特高拱坝时效变形的空间非线性协整关系转化为区域内近似线性的协整关系，建立了描述大坝不同部位时变协整发展规律的分区协整模型，通过协整残差实现了多测点时效变形的协整发展监控和预警。

实测变形资料作为特高拱坝服役性态最直观的表征，蕴藏着丰富的时空信息和演变规律。为研究特高拱坝时效变形的协整性，利用小波分解获得大坝位移的时效分量，考虑到特高拱坝的空间整体一致性差异，采用FCM聚类算法实现了时效变形的区域化，借助区域线性化思想，将整个特高拱坝时效变形的空间非线性协整关系转化为区域内近似线性的协整关系，建立了描述大坝不同部位时变协整发展规律的分区协整模型，通过协整残差实现了多测点时效变形的协整发展监控和预警。

The measured deformation data contain rich temporal and spatial information and evolution laws of dam deformation. To study the co-integration relationship of the aging deformation of extra-high arch dams, wavelet decomposition was firstly used to obtain the aging component of the dam displacement. Considering the weak spatial integrity of extra-high arch dams, the FCM clustering algorithm was utilized to realize the regionalization of aging deformation. With the help of the idea of regional linearization, the spatial nonlinear co-integration relationship of the whole dam aging deformation was transformed into several approximate linear co-integration relationships within different regions. The zonal co-integration model was established to describe the development law of time-varying co-integration in different regions of the dam. The co-integration development monitoring and early warning of multi-measuring points aging deformation were realized by co-integration residual.
