| 摘 要： | 建立变形与时间相关关系的变形模型，从中找出变形与时间相关关系的最佳变形模型；再建立变形与水位相关关系的变形模型，从中找出变形与水位相关关系的最佳变形模型；然后以变形与时间相关关系及变形与水位相关关系的最佳变形模型为基础，建立变形与时间、水位相关关系的变形模型，最后将变形与时间、水位相关关系的变形模型的模型参数作为状态向量，用卡尔曼滤波法进行大坝变形分析，实例计算表明这种建模方法效果较好．

| Abstract: | The paper uses the method of reference 1 to choose the deformation models that the deformation has something to do with time,and the best model is chosen in these models;then the deformation models that the deformation! has something to do with water level are chosen,and the best model is chosen in these models.On the basis of the model that the deformation has something to do with time and the model that deformation has something to do with water level ;a deformation model that the deformation has something to do with time and water level is chosen.Finally,the parameters of the model that the deformation has something to do with time and water level are looked as the status vectors,and Kalman filter method is used to do deformation analysis of the dam.The example calculation shows that the method to choose model is effective. |
