Grey prediction model of dam deformation of XiaoLangdi multi purpose project

ZHANG Yong-guang~(①④),WANG Lan-feng~(②),LU Kai-yun~(③)(①Institute of Surveying &Mapping Information Engineering,YREC,Zhengzhou 450045,China;②North China Institute of Water Conservancy and Hydroelectric Power,Zhengzhou 450008,China;③East China Institute of Technology,Jiangxi Fuzhou 344000,China;④State Key Laboratory of information Engineering in Surveying,Mapping and Remote Sensing,Wuhan University,Wuhan 430079,China)  
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.
