| Abstract: | Based on analysis of prediction methods of the dam deformation,a GM(1,1) model for the deformation of the dam of Xiaolangdi multipurpose project has been proposed with grey theory and methods practically applied for the first time.The displacement of some observation sites is predicted by means of this model.The satisfactory effect is achieved through the modeling and computation.The predication accuracy proves that the model can be used in practice.Moreover,it also provides the important basis for the dam safety. |
