Multi Scale Information Fusion Predicating Model of Gravity Dam Deformation

摘要

Taken gravity dam deformation as random variables, multi-scale manifestation has been taken on deformation to build multi-scale statistical model based on multi-scale system theory. Then dam monitoring system has been transformed to integrate deformation monitoring information in the multi-scale domain. Furthermore, the multi scale information fusion estimation model has been established. At last, the predicating model of gravity dam deformation has been built with EWKHEFA algorithm using standardized Kalman filter. These methods have been applied into an actual project and the result shows that the model can be used into gravity dam deformation prediction effectively.
