Presentation of an Extended Surface Finite Element Method to Model the Deformation of Structures Continually; Case Study: Karkhe Earth Dam

A deformation modeling method for structures based on a new adaptive methodology by implementation of inter-element continuity constraints is presented in this paper. Estimating the proper relative weight of each sensor observation. Developing an extended surface fnite element method (ESFEM), the differential equations of deformation with inter-element continuity constraints are solved.Furthermore, this method provides the possibility of fusion of non-synchronized repetitious geotechnical and geodetic observations as the boundary data to model the deformation with respect to an inertial reference frame. Also the proper weight of multi-sensor’s observations would be estimated.
