| Abstract: | Taking consideration of the integrity modeling with correlative multiple deformation points,this paper extends the single point deformation analysis into spatial multi-point integrity analysis and presents a non-equidistant multi-point modeling by improving equispacing processing for the non-equidistant series. The real practical analysis and comparative results indicate that the non-equidistant multi-point prediction model is feasible and effective,which is a new nonlinear approach to the integrated deformation analysis and prediction in time and space domain. |
