Outline
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.
